e turned his back to run。 〃He was？〃 called Fischer inquiringly。 〃A real policeman；〃 said Father Brown； and ran away into the dark。 There were hollows and bowers at the extreme end of that leafy garden； in which the laurels and other immortal shrubs showed against sapphire sky and silver moon； even in that midwinter； warm colours as of the south。 The green gaiety of the waving laurels； the rich purple indigo of the night； the moon like a monstrous crystal； make an almost irresponsible romantic picture； and among the top branches of the garden trees a strange figure is climbing； who looks not so much romantic as impossible。 He sparkles from head to heel； as if clad in ten million moons； the real moon catches him at every movement and sets a new inch of him on fire。 But he swings； flashing and successful； from the short tree in this garden to the tall； rambling tree in the other； and only stops there because a shade has slid under the smaller tree and has unmistakably called up to him。 〃Well； Flambeau；〃 says the voice； 〃you really look like a Flying Star； but that always means a Falling Star at last。〃 The silver； sparkling figure above seems to lean forward in the laurels and； confident of escape； listens to the little figure below。 〃You never did anything better； Flambeau。 It was clever to come from Canada （with a Paris ticket； I suppose） just a week after Mrs。 Adams died； when no one was in a mood to ask questions。 It was cleverer to have marked down the Flying Stars and the very day of Fischer's coming。 But there's no cleverness； but mere genius； in what followed。 Stealing the stones； I suppose； was nothing to you。 You could have done it by sleight of hand in a hundred other ways besides that pretence of putting a paper donkey's tail to Fischer's coat。 But in the rest you eclipsed yourself。〃 The silvery figure among the green leaves seems to linger as if hypnotised； though his escape is easy behind him； he is staring at the man below。 〃Oh； yes；〃 says the man below； 〃I know all about it。 I know you not only forced the pantomime； but put it to a double use。 You were going to steal the stones quietly； news came by an accomplice that you were already suspected； and a capable police officer was coming to rout you up that very night。 A common thief would have been thankful for the warning and fled； but you are a poet。 You already had the clever notion of hiding the jewels in a blaze of false stage jewellery。 Now； you saw that if the dress were a harlequin's the appearance of a policeman would be quite in keeping。 The worthy officer started from Putney police station to find you； and walked into the queerest trap ever set in this world。 When the front door opened he walked straight on to the stage of a Christmas pantomime； where he could be kicked； clubbed； stunned and drugged by the dancing harlequin； amid roars of laughter from all the most respectable people in Putney。 Oh； you will never do anything better。 And now； by the way； you might give me back those diamonds。〃 The green branch on which the glittering figure swung； rustled as if in astonishment； but the voice went on： 〃I want you to give them back； Flambeau； and I want you to give up this life。 There is still youth and honour and humour in you； don't fancy they will last in that trade。 Men may keep a sort of level of good； but no man has ever been able to keep on one level of evil。 That road goes down and down。 The kind man drinks and turns cruel； the frank man kills and lies about it。 Many a man I've known started like you to be an honest outlaw； a merry robber of the rich； and ended stamped into slime。 Maurice Blum started out as an anarchist of principle； a father of the poor； he ended a greasy spy and tale…bearer that both sides used and despised。 Harry Burke started his free money movement sincerely enough； now he's sponging on a half…starved sister for endless brandies and sodas。 Lord Amber went into wild society in a sort of chivalry； now he's paying blackmail to the lowest vultures in London。 Captain Barillon was the great gentleman…apache before your time； he died in a madhouse； screaming with fear of the 〃narks〃 and receivers that had betrayed him and hunted him down。 I know the woods look very free behind you； Flambeau； I know that in a flash you could melt into them like a monkey。 But some day you will be an old grey monkey； Flambeau。 You will sit up in your free forest cold at heart and close to death； and the tree…tops will be very bare。〃 Everything continued still； as if the small man below held the other in the tree in some long invisible leash； and he went on： 〃Your downward steps have begun。 You used to boast of doing nothing mean； but you are doing something mean tonight。 You are leaving suspicion on an honest boy with a good deal against him already； you are separating him from the woman he loves and who loves him。 But you will do meaner things than that before you die。〃 Three flashing diamonds fell from the tree to the turf。 The small man stooped to pick them up； and when he looked up again the green cage of the tree was emptied of its silver bird。 The restoration of the gems （accidentally picked up by Father Brown； of all people） ended the evening in uproarious triumph； and Sir Leopold； in his height of good humour； even told the priest that though he himself had broader views； he could respect those whose creed required them to be cloistered and ignorant of this world。
The Invisible Man
In the cool blue twilight of two steep streets in Camden Town； the shop at the corner； a confectioner's； glowed like the butt of a cigar。 One should rather say； perhaps； like the butt of a firework； for the light was of many colours and some complexity； broken up by many mirrors and dancing on many gilt and gaily…coloured cakes and sweetmeats。 Against this one fiery glass were glued the noses of many gutter…snipes； for the chocolates were all wrapped in those red and gold and green metallic colours which are almost better than chocolate itself； and the huge white wedding…cake in the window was somehow at once remote and satisfying； just as if the whole North Pole were good to eat。 Such rainbow provocations could naturally collect the youth of the neighbourhood up to the ages of ten or twelve。 But this corner was also attractive to youth at a later stage； and a young man； not less than twenty…four； was staring into the same shop window。 To him； also； the shop was of fiery charm； but this attraction was not wholly to be explained by chocolates； which； however； he was far from despising。 He was a tall； burly； red…haired young man； with a resolute face but a listless manner。 He carried under his arm a flat； grey portfolio of black…and…white sketches； which he had sold with more or less success to publishers ever since his uncle （who was an admiral） had disinherited him for Socialism； because of a lecture which he had delivered against that economic theory。 His name was John Turnbull Angus。 Entering at last； he walked through the confectioner's shop to the back room； which was a sort of pastry…cook restaurant； merely raising his hat to the young lady who was serving there。 She was a dark； elegant； alert girl in black； with a high colour and very quick； dark eyes； and after the ordinary interval she followed him into the inner room to take his order。 His order was evidently a usual one。 〃I want； please；〃 he said with precision； 〃one halfpenny bun and a small cup of black coffee。〃 An instant before the girl could turn away he added； 〃Also； I want you to marry me。〃 The young lady of the shop stiffened suddenly and said； 〃Those are jokes I don't allow。〃 The red…haired young man lifted grey eyes of an unexpected gravity。 〃Really and truly；〃 he said； 〃it's as seriousas serious as the halfpenny bun。 It is expensive； like the bun； one pays for it。 It is indigestible； like the bun。 It hurts。〃 The dark young lady had never taken her dark eyes off him； but seemed to be studying him with almost tragic exactitude。 At the end of her scrutiny she had something like the shadow of a smile； and she sat down in a chair。 〃Don't you think；〃 observed Angus； absently； 〃that it's rather cruel to eat these halfpenny buns？ They might grow up into penny buns。 I shall give up these brutal sports when we are married。〃 The dark young lady rose from her chair and walked to the window； evidently in a state of strong but not unsympathetic cogitation。 When at last she swung round again with an air of resolution she was bewildered to observe that the young man was carefully laying out on the table various objects from the shop…window。 They included a pyramid of highly coloured sweets； several plates of sandwiches； and the two decanters containing that mysterious port and sherry which are peculiar to pastry…cooks。 In the middle of this neat arrangement he had carefully let down the enormous load of white sugared cake which had been the huge ornament of the window。 〃What on earth are you doing？〃 she asked。 〃Duty； my dear Laura；〃 he began。 〃Oh； for the Lord's sake； stop a minute；〃 she cried； 〃and don't talk to me in that way。 I mean； what is all that？〃 〃A ceremonial meal； Miss Hope。〃 〃And what is that？〃 she asked impatiently； pointing to the mountain of sugar。 〃The wedding…cake； Mrs。 Angus；〃 he said。 The girl marched to that article； removed it with some clatter； and put it back in the shop window； she then returned； and； putting her elegant elbows on the table； regarded the young man not unfavourably but with considerable exasperation。 〃You don't give me any time to think；〃 she said。 〃I'm not such a fool；〃 he answered； 〃that's my Christian humility。〃 She was still looking at him； but she had grown considerably graver behind the smile。 〃Mr。 Angus；〃 she said steadily； 〃before there is a minute more of this nonsense I must tell you something about myself as shortly as I can。'〃 〃Delighted；〃 replied Angus gravely。 〃You might tell me something about myself； too； while you are about it。〃 〃Oh； do hold your tongue and listen；〃 she said。 〃It's nothing that I'm ashamed of； and it isn't even anything that I'm s
