until given permission.â
âSome Christmas surprise,â put in a thin lady, ceasing to eat nuts and raisins for the first time since dinner, and nodding brightly as she patted her hair. âIâve heard of such things before. Sometimes they have someone to call dressed as Santa Claus, and every guest gets a gift.â
âWhen?â said a small, sandy man with a tartan tie, emerging from his nap.
âQuite an idea,â agreed Mr Mullinger.
âConfined to barracks, by Gad,â snapped the colonel fiercely, and reached for the decanter.
There came a discreet hurricane of fluttering applause from the table across the room. Young Glover had just completed another conjuring trick.
âWhatâs the noise about?â demanded the old colonel, preening his moustache, and vaguely trying to light a match with a cigarette.
âAstoundinâ,â remarked a stout commercial traveller. âDipped a piece of white paper right into a glass of ink? anâ when he pulled the paper out again? it was all black but the ink in the glass had changed to pure water. Makes Maskylion look silly he does; makes Maskylion look silly. Dipped a piece of white paperââ

âQuite simple,â said young Glover modestly. âYou see it was only a glass of clean water with some black silk inside the glass, sticking lightly against the side. When I stuck the paper in the water I drew it out with the black silk on it.â
There was enthusiastic applause.
âTalking about conjuring,â said Mr Mullinger lightly, âI once heard a chap say that it was possible for him to leave a glass full of water on a table in the room, that he would go out, and when he walked into the room again within a few minutes, the glass would be empty.â
âConfederate in the room,â said the stout dowager excitedly.
âNo, he said not,â said Mr Mullinger. âNo one else in the room was to touch the glass at all. All bunk, of course. Quite impossible. I would bet a sovereign it couldnât be done. Donât know whether the chap was trying to impress us with psychic stuff or whatever you call it, butââ
âI could do it!â

Mr Mullinger stared at Eric Gloverâs eager face with surprise.
âYou would leave a glass full of water inside this room, go out, and when you walked in again the glass would be empty. Impossible!â
âYou spoke about a pound bet,â said Mr Glover playfully. âIâll call you!â
Mr Mullinger stared in silence. Chairs scraped near in an interested circle.
âThere is a glass here,â said the ancient Mr Warboys, snapping his upper set more tightly into position.
âI shall want that,â snapped the old colonel, irritably removing the otherâs fingers from the stem. What about that glass young Glover has been using? Use that, dammit!â
âIâd like to see that glass,â muttered Mr Mullinger. He got up, examined the glass carefully and flicked it ringingly with his fingernail.
âNo false bottom there,â grinned Glover.
âLetâs know where we stand,â grunted the older man. âDo you know what you have undertaken to do?â
Glover nodded.
âI will go out of this room, leaving that glass full of water. No one else is to touch it; it shall stand on the table in full view of everybody. When I walk in againâwhich I shall do within five minutes of walking outâthe glass will still be on the table BUT EMPTY.â
âImpossible,â declared Mr Mullinger.
Glover smiled quietly. He filled the glass from a decanter of water and set it on the table, where it stood palely agleam against the dark polish of the oak.
âI know a good way of keeping milk from going sour,â put in the commercial traveller suddenly.
âWhat way?â demanded a sour-looking woman, looking up from a woollen pullover she was committing for a
