"But the body—where is it?" I asked.
"I've been to the British Museum to-day," said Quarles, taking up the rough sketch from his desk. "This is a copy of an old map of the Finsbury district, and here I find was one of the old plague pits. I believe Portman's house stands on this plot."
It was a very rough sketch, but, as I compared the place the professor had indicated with the old landmarks and their modern equivalents which he had marked, there could be little doubt that Quarles was right.
"I do not suppose that Portman's is the first body that has passed through that chest and slid down into some hole which was once a part of this pit," he went on. "I asked Mrs. Eccles about a squinting youth. He was a young fool with expectations, just such another as Lord Stanford. He was robbed right and left, and it is quite certain Portman, among others, made money out of him. He disappeared suddenly. It is possible Lord Stanford might have disappeared in a similar way had not his friends got him out of the country. Portman didn't have that chest fixed to the floor of his room for nothing. You may find the solution to more than one mystery, Wigan, when you move that chest."
Portman's body and the remains of at least three other bodies were found in the deep hole under the old house in Finsbury. How the hole had come there, or how Portman had discovered it, it was impossible to guess, but there could be little doubt that he had only been treated as he had treated others. And some six months afterward a man named Postini was knifed in Milan, and the inquiry into his murder brought to light the fact that he had been closely connected with Portman. They had worked together in London, in Paris, and in Rome. At the time of Portman's death they had quarreled, and at that time Postini was in London. Among Portman's papers I found none relating to Postini; no doubt the Italian had taken them, for Portman's letter, asking him to dine and to become true friends again, was found among the Italian's papers.
There can be little doubt, I think, that Quarles was right. Portman intended to rid himself of the Italian after giving him a sumptuous feast, but Postini, wholly distrusting his former comrade, had come a day before his time, and been the murderer instead of the victim.
CHAPTER XVI
THE SEARCH FOR THE MISSING FORTUNE
Whenever he had solved a case, if not to the world's satisfaction, to his own, Quarles seldom mentioned it again. He professed to think little of his achievement, a pose which I have no doubt concealed a considerable amount of satisfaction and self-complacency. Of the curious case connected with the Bryants, he was, however, rather proud; and, since it resulted in making things easier for Zena and me, I have every reason to be satisfied.
It began in a strange way. A simple looking old man, his clothes a size too large for him, walked into a large pawnbroker's one day, and, handing him a scarf-pin, asked how much could be given for it. The pin was no use to him. He didn't want to pawn it, but to sell it. The customer was requested to put a price upon his property, and, after some hesitation, he asked whether twenty pounds would be too much. The man in the shop went into a back room ostensibly to consult his superior, in reality to send for the police. It happened that a quantity of jewelry had been stolen from a well-known society lady a few weeks before, and pawnbrokers had had special notice of the fact; hence the firm's precaution. The simple old man had offered for twenty pounds a diamond that was worth at least twenty times that amount.
