With a puzzled look he turned smartly round and disappeared once more into the kitchen.
«Very interesting,» said Dirk quietly, «I wondered if his memory might be poor.»
He stood, suddenly, and prowled around the room. His eyes fell on the abacus which stood on the only clear space on the large mahogany table.
«Is this the table,» he asked Richard in a low voice, «where you found the note about the salt cellar?»
«Yes,» said Richard, standing, and coming over, «tucked into this book.» He picked up the guide to the Greek islands and flipped through it.
«Yes, yes, of course,» said Dirk, impatiently. «We know about all that. I'm just interested that this was the table.» He ran his fingers along its edge, curiously.
«If you think it was some sort of prior collaboration between Reg and the girl,» Richard said, «then I must say that I don't think it possibly can have been.»
«Of course it wasn't,» said Dirk testily, «I would have thought that was perfectly clear.»
Richard shrugged in an effort not to get angry and put the book back down again.
«Well, it's an odd coincidence that the book should have been…»
«Odd coincidence!» snorted Dirk. «Ha! We shall see how much of a coincidence. We shall see exactly how odd it was. I would like you, Richard, to ask our friend how he performed the trick.»
«I thought you said you knew already.»
«I do,» said Dirk airily. «I would like to hear it confirmed.»
«Oh, I see,» said Richard, «yes, that's rather easy, isn't it? Get him to explain it, and then say, „Yes, that's exactly what I thought it was!“ Very good, Dirk. Have we come all the way up here in order to have him explain how he did a conjuring trick? I think I must be mad.»
Dirk bridled at this.
«Please do as I ask,» he snapped angrily. «You saw him do the trick, you must ask how he did it. Believe me, there is an astounding secret hidden within it. I know it, but I want you to hear it from him.»
He spun round as Reg re-entered, bearing a tray, which he carried round the sofa and put on to the low coffee table that sat in front of the fire.
«Professor Chronotis…» said Dirk.
«Reg,» said Reg, «please.»
«Very, well,» said Dirk, «Reg…»
«Sieve!» exclaimed Reg.
«What?»
«Thing you drain rice in. A sieve. I was trying to remember the word, though I forget now the reason why. No matter. Dirk, dear fellow, you look as if you are about to explode about something. Why don't you sit down and make yourself comfortable?»
«Thank you, no, I would rather feel free to pace up and down fretfully if I may. Reg…»
He turned to face him square on, and raised a single finger.
«I must tell you,» he said, «that I know your secret.»
«Ah, yes, er — do you indeed?» mumbled Reg, looking down awkwardly and fiddling with the cups and teapot. «I see.»
The cups rattled violently as he moved them. «Yes, I was afraid of that.»
«And there are some questions that we would like to ask you. I must tell you that I await the answers with the very greatest apprehension.»
«Indeed, indeed,» Reg muttered. «Well, perhaps it is at last time. I hardly know myself what to make of recent events and am… fearful myself. Very well. Ask what you will.» He looked up sharply, his eyes glittering.
Dirk nodded curtly at Richard, turned, and started to pace, glaring at the floor.
«Er,» said Richard, «well. I'd be… interested to know how you did the conjuring trick with the salt cellar last night.»
Reg seemed surprised and rather confused by the question. «The conjuring trick?» he said.
«Er, yes,» said Richard, «the conjuring trick.»
«Oh,» said Reg, taken aback, «well, the conjuring part of it, I'm not sure I should — Magic Circle rules, you know, very strict about revealing these secrets. Very strict. Impressive trick, though, don't you think?» he added slyly.
«Well, yes,» said Richard, «it seemed very natural at the time, but now that I… think about it, I have to admit that it was a bit dumbfounding.»
«Ah, well,» said Reg, «it's skill. you see. Practice. Make it look natural.»
«It did look very natural,» continued Richard, feeling his way, «I was quite taken in.»
«You liked it?»
«It was very impressive.»
Dirk was getting a little impatient. He shot a look to that effect at Richard.
«And I can quite see,» said Richard firmly, «why it's impossible for you to tell me. I was just interested, that's all. Sorry I asked.»
«Well,» said Reg in a sudden seizure of doubt, «I suppose… well, so long as you absolutely promise not to tell anyone else.» he carried on, «I suppose you can probably work out for yourself that I used two of the salt cellars on the table. No one was going to notice the difference between one and another. The quickness of the hand, you know, deceives the eye, particularly some of the eyes around that table. While I was fiddling with my woolly hat, giving, though I say so myself, a very cunning simulation of clumsiness and muddle, I simply slipped the salt cellar down my sleeve. You see?»
His earlier agitation had been swept away completely by his pleasure in showing off his craft.
«It's the oldest trick in the world, in fact,» he continued, «but nevertheless takes a great deal of skill and deftness. Then a little later, of course, I returned it to the table with the appearance of simply passing it to someone else. Takes years of practice, of course, to make it look natural, but I much prefer it to simply slipping the thing down to the floor. Amateur stuff that. You can't pick it up, and the cleaners never notice it for at least a fortnight. I once had a dead thrush under my seat for a month. No trick involved there, of course. Cat killed it.»
Reg beamed.
Richard felt he had done his bit, but hadn't the faintest idea where it was supposed to have got them. He glanced at Dirk, who gave him no help whatsoever, so he plunged on blindly.
«Yes,» he said, «yes, I understand that that can be done by sleight of hand. What I don't understand is how the salt cellar got embedded in the pot.»
Reg looked puzzled once again, as if they were all talking at cross purposes. He looked at Dirk, who stopped pacing and stared at him with bright, expectant eyes.
«Well, that's… perfectly straightforward,» said Reg, «didn't take any conjuring skill at all. I nipped out for my hat, you remember?»
«Yes,» said Richard, doubtfully.
«Well,» said Reg, «while I was out of the room I went to find the man who made the pot. Took some time, of course. About three weeks of detective work to track him down and another couple of days to sober him up, and then with a little difficulty I persuaded him to bake the salt cellar into the pot for me. After that I briefly stopped off somewhere to find some, er, powder to disguise the suntan, and of course I had to time the return a little carefully so as to make it all look natural. I bumped into myself in the ante-room, which I always find embarrassing, I never know where to look, but, er… well, there you have it.»
He smiled a rather bleak and nervous smile.
Richard tried to nod, but eventually gave up.
«What on earth are you talking about?» he said.
Reg looked at him in surprise.
«I thought you said you knew my secret,» he said.
«I do,» said Dirk, with a beam of triumph. «He, as yet, does not, though he furnished all the information I needed to discover it. Let me,» he added, «fill in a couple of little blanks. In order to help disguise the fact that you had in fact been away for weeks when as far as anyone sitting at the table was concerned you had only popped out of the door for a couple of seconds, you had to write down for your own reference the last thing you said, in order that you could pick up the thread of conversation again as naturally as possible. An important detail if your memory is not what it once was. Yes?»
