“What?” asked Selwood.

“That he’s not afraid of being recaptured as you’d think he would be,” replied the Professor. “It suggests that he’s got some card up his sleeve—which is what I’ve always thought. He probably knows something—you may be certain, in any case, that he’s playing a deep and bold game, for his own purpose, of course. Now, I wonder if Burchill went to that restaurant on the same errand as yourself?”

“What!—to look for Dimambro?” exclaimed Selwood.

“Why not? Remember that Burchill was Jacob Herapath’s secretary before you were,” answered the Professor. “He was with Jacob some time, wasn’t he? Well, he knew a good deal about Jacob’s doings. Jacob may have had dealings with this Dimambro person in Burchill’s days. You don’t remember that Jacob had any such dealings in your time?”

“Never!” replied Selwood. “Never heard the man’s name until yesterday—never saw any letters from him, never heard Mr. Herapath mention him. But then, as Mr. Halfpenny said, yesterday, Mr. Herapath had all sorts of queer dealings with queer people. It’s a fact that he used to buy and sell all sorts of things—curios, pictures, precious stones—he’d all sorts of irons in the fire. It’s a fact, too, that he was accustomed to carrying not only considerable sums of money, but valuables on him.”

“Ah!” exclaimed the Professor. He rose out of his chair, put his hands behind his broad back, and began to march up and down his study. “I’ll tell you what, young man!” he said earnestly. “I’m more than ever convinced that Jacob Herapath was robbed as well as murdered, and that robbery and murder—or, rather, murder and robbery, for the murder would go first—took place just before Barthorpe entered the offices to keep that appointment. Selwood!—we must find this Dimambro man!”

“Who’s most likely left the country,” remarked Selwood.

“That’s probable—it may be certain,” said the Professor. “Nevertheless, he may be here. And Burchill may be looking for him, too. Now, if Dimambro stopped two days at that Hotel Ravenna, from November 11th to 13th, there must be somebody who knows something of him. We must—you must—make more inquiry—there at the hotel. Talk quietly to that manager or the servants. Get a description of him. Do that at once—first thing tomorrow morning.”

“You don’t want to tell the police all this?” asked Selwood.

“No! Not at present, at any rate,” answered the Professor. “The police have their own methods, and they don’t thank anybody for putting them off their beaten tracks. And—for the present—we won’t tell them anything about your seeing Burchill. If we did, they’d be incredulous. Police-like, they’ll have watched the various seaports much more closely than they’ll have watched London streets for Burchill. And Burchill’s a clever devil—he’ll know that he’s much safer under the very nose of the people who want him than he would be fifty miles away from their toes! No, it’s my opinion that Master Burchill will reveal himself, when the time comes.”
