Rubin said, "Maybe it was the attache case he took."

"No, no, that was Jackson's. He'd owned it for years. So there you have the problem. Anderson wanted me to find out what had been taken, for until he could identify a stolen object and show that the object was, or had been, in the possession of Jackson, he could not prosecute-and he was most intent on prosecution. My task, then, was to look through his house and tell him what was missing."

"How would that be possible, if he himself couldn't tell?" growled Trumbull.

"I pointed that out to him," said Bartram, "but he was wild and unreasoning. He offered me a great deal of money, win or lose; a very handsome fee, indeed, and he put down a sizable portion of it as a retainer. It was clear he resented beyond measure the deliberate insult to his acquisitiveness. The thought that an amateur non-acquis-itor like Jackson should dare beard him in this most sacred of his passions had driven him, on this one point, mad, and he was prepared to go to any expense to keep the other's victory from being final.

"I am myself quite human. I accepted the retainer and the fee. After all, I reasoned, I had my methods. I took up the question of insurance lists first. All were outdated, but they served to eliminate the furniture and all the larger items as possible victims of Jackson's thievery, for everything on the lists was still in the house."

Avalon interrupted. "They were eliminated anyway, since the stolen object would have had to fit into the attache case."

"Provided that it was indeed the attache case that was used to transport the item out of the house," pointed out Bartram patiendy. "It might easily have been a decoy. Prior to Anderson's return, Jackson could have had a moving van at the door and taken out the grand piano had he so chosen, and then snapped the attache case in Anderson's face to mislead him.

"But never mind that. It wasn't likely. I took him around the house room by room, following a systematic procedure of considering the floor, walls, and ceiling, studying all the shelves, opening every door, considering every piece of furniture, going through every closet. Nor did I neglect the attic and the basement. Never before had Anderson been forced to consider every item of his vast and amorphous collection in order that somewhere, somehow, some item would jog his memory of some companion item that was not there.

"It was an enormous house, a heterogeneous one, an endless one. It took us days, and poor Anderson grew more befuddled each day.

"I next tackled it from the other end. It was obvious that Jackson had deliberately taken something unnotice-able, perhaps small; certainly something that Anderson would not easily miss and therefore not something to which he was greatly attached. On the other hand, it made sense to suppose that it was something Jackson would want to take away, and which he would find valuable. Indeed, his deed would give him most satisfaction if Anderson, too, found it valuable-once he realized what it was that was gone. What, then, could it be?"

"A small painting," said Gonzalo eagerly, "which Jackson knew to be an authentic Cezanne, but which Anderson thought was junk."

"A stamp from Anderson's collection," said Rubin, "which Jackson noted had a rare mistake in the engraving." He had once written a story which had hinged on this precise point.

"A book," said Trumbull, "which contained some hidden family secret with which, in due time, Jackson could blackmail Anderson."

"A photograph," said Avalon dramatically, "that Anderson had forgotten but which contained the likeness of an old sweetheart which, eventually, he would give a fortune to buy back."

"I don't know what business they were in," said Drake thoughtfully, "but it might have been the kind where some unvalued gimcrack might actually be of great value to a competitor and drive Anderson to bankruptcy. I remember one case where a formula for a hydrazo-intermediate-"

"Oddly enough," said Bartram, breaking in firmly, "I thought of each of these possibilities, and I went over each with Anderson. It was clear that he had no taste in art and such pieces as he had were really junk, and no mistake. He did not collect stamps, and though he had many books and could not tell for certain whether one was gone, he swore he had no hidden family secrets anywhere that were worth the skipped beat of a blackmailer's heart. Nor had he ever had any old sweethearts, since in his younger days he had confined himself to professional ladies whose photographs he did not prize. As for his business secrets, they were of the sort that would interest the government far more than any competitor, and everything of that sort had been kept far from Jackson's honest eyes in the first place and were still in the safe (or long in the fire) in the second. I thought of other possibilities, but, one by one, they were knocked down.

"Of course, Jackson might betray himself. He might blossom out into sudden wealth, and in ferreting out the source of the wealth, we might learn the identity of the stolen object.

"Anderson suggested that himself and paid lavishly to have a twenty-four-hour watch put on Jackson. It was useless. The man kept a dull way of life and behaved precisely as you would expect someone minus his life savings to behave. He lived parsimoniously, and, eventually, took a menial job, where his honesty and his calm demeanor stood him in good stead.

"Finally, I had but one alternative left-" "Wait, wait," said Gonzalo, "let me guess, let me guess." He tossed off what was left of his brandy, signaled Henry for another, and said, "You asked Jackson!"

"I was strongly tempted to," said Bartram ruefully, "but that would scarcely have been feasible. It doesn't do in my profession to even hint at an accusation without evidence of any sort. Licenses are too fragile. And in any case, he would simply deny theft, if accused, and be put on his guard against any self-incrimination."

"Well, then…," said Gonzalo blankly, and petered out.

The other four furrowed brows one and all, but only silence followed.

Bartram, having waited politely, said, "You won't guess, gentlemen, for you are not in the profession. You know only what you read in romances and so you think gentlemen like myself have unlimited numbers of alternatives and invariably solve all cases. I, myself, being in the profession, know otherwise. Gentlemen, the one alternative I had left was to confess failure.

"Anderson paid me, however, I'll give him that much credit. By the time I said my goodbyes to him, he had lost some ten pounds. There was a vacant look in his eyes and, as he shook hands with me, they moved round and round the room he was in, still looking, still looking. He muttered, 'I tell you I couldn't possibly mistake that chuckle. He took something from me. He took something from me.'

"I saw him on two or three occasions thereafter. He never stopped looking; he never found the missing object.

He went rather downhill. The events I have described took place nearly five years ago, and last month, he died."

There was a short silence. Avalon said, "Without ever finding the missing object?"

"Without ever finding it."

Trumbull said, with disapproval, "Are you coming to us to help you with the problem now?"

"In a way, yes. The occasion is too good to miss. Anderson is dead and whatever is said within these walls will go no farther, we all agree, so that I may now ask what I could not ask before… Henry, may I have a light?"

Henry, who had been listening with a kind of absent-minded deference, produced a book of matches and lit Bartram's cigarette.

"Let me introduce you, Henry, to those you so efficiently serve… Gentlemen, may I introduce to you, Henry Jackson."

There was a moment of clear shock and Drake said, "The Jackson."
