“I speak it—you understand—enough to say a good many words—but not so good as him,” observed Mr. Dimambro, waving a fat hand. “He say it for me—for both of us, eh?”

“To be sure, sir, to be sure,” said Davidge. “Mr. Burchill is gifted that way, of course. Well, Mr. Burchill, and what might this story be, now? Deeply interesting, I’ll be bound.”

Burchill pulled a chair to the table, opposite Selwood and the Professor. He put the tips of his fingers together and assumed an explanatory manner.

“I shall have to begin at the beginning,” he said. “You’ll all please to follow me closely. Now, to commence—Mrs. Engledew permits me to speak for her as well as for Mr. Dimambro. The fact is, I can put the circumstances of the whole affair into a consecutive manner. And I will preface what I have to say by making a statement respecting a fact in the life of the late Mr. Herapath which will, I believe, be substantiated by Mr. Selwood, my successor as secretary to the deceased gentleman. Mr. Herapath, in addition to being an authority on the building of up-to-date flats, was also more or less of an expert in precious stones. He not only bought and sold in these things, but he gave advice to his friends in matters relating to them. Mr. Selwood has, I am sure, had experience of that fact?”

“To a certain extent—yes,” agreed Selwood. “But I had not been long enough in Mr. Herapath’s employ to know how much he went in for that sort of thing.”

“That is immaterial,” continued Burchill. “We establish the fact that he did. Now we come to the first chapter of our story. This lady, Mrs. Engledew, a tenant of this flat since the Herapath Estate was built, is an old acquaintance—I am permitted to say, friend—of the late Jacob Herapath. She occasionally consulted him on matters of business. On November 12th last she consulted him on another affair—though it had, of course, a business complexion. Mrs. Engledew, by the death of a relative, had just come into possession of some old family jewels—chiefly diamonds. These diamonds, which, Mrs. Engledew tells me, had been valued by Spinks at about seven thousand pounds, were in very old, considerably worn settings. Mrs. Engledew wished to have them reset. Knowing that Jacob Herapath had great taste and knowledge in that direction, she saw him at his office on the noon of November 12th, showed him the diamonds, and asked his advice. Jacob Herapath—I am giving you Mrs. Engledew’s account—told her to leave the diamonds with him, as he was going to see, that very day, an expert in that line, to whom he would show the stones with the idea of his giving him his opinion on what ought to be done with them. Mrs. Engledew handed him the diamonds in a small case, which he put in his pocket. I hope,” added Burchill, turning to Mrs. Engledew, “that I have given all this quite correctly?”

“Quite,” assented Mrs. Engledew. “It is perfectly correct.”

“Then,” continued Burchill, “we pass on to Mr. Dimambro. Mr. Luigi Dimambro is a dealer in precious stones, who resides in Genoa, but travels widely about Europe in pursuance of his business. Mr. Dimambro had had several dealings with Jacob Herapath during past years, but previous to November 12th last they had not met for something like twelve months. On their last previous meeting Jacob Herapath told Mr. Dimambro that he was collecting pearls of a certain sort and size—specimens of which he showed him—with a view to presenting his niece, Miss Wynne, with a necklace which was to be formed of them. He gave Dimambro a commission to collect such pearls for him. On November 11th last Dimambro arrived in London from the Continent, and wrote to Mr. Herapath to tell him of his arrival, and to notify him that he had brought with him some pearls of the sort he wanted. Mr. Herapath thereupon made an appointment with Dimambro at the House of Commons on the evening of November 12th at half-past ten o’clock. Dimambro kept that appointment, showed Mr. Herapath the pearls which he had brought, sold them to him, and received from him, in payment for them, a cheque for three thousand guineas. This transaction being conducted, Mr. Herapath drew from his pocket (the same pocket in which he had already placed the pearls, which I understand, were wrapped up in a small bag or case of wash-leather) the diamonds which Mrs. Engledew had entrusted to him, showed them to Dimambro, and asked his opinion as to how they could best be reset. It is not material to this explanation to repeat what Dimambro said on that matter—suffice it to say that Dimambro gave an expert opinion, that Mr. Herapath once more pocketed the diamonds, and soon afterwards left the House of Commons for his estate offices with both lots of valuable stones in his possession—some ten thousand pounds’ worth in all. As for Dimambro, he went home to the hotel at which he was stopping—a little place called the Ravenna, in Soho, an Italian house—next morning, first thing, he cashed his cheque, and before noon he left for the Continent. He had not heard of the murder of Jacob Herapath when he left London, and he did not hear of it until next day. I think I have given Mr. Dimambro’s account accurately—his account so far,” concluded Burchill, turning to the Italian. “If not, he will correct me.”

“Quite right, quite right!” said Dimambro, who had listened eagerly. “I do not hear of the murder, eh, until I am in Berlin—it is, yes, next day—day after I leave London—that I hear of it, you understand? I then see it in the newspaper—English news, eh?”

“Why did you not come back at once?” asked Cox-Raythwaite.
