“Impossible, my dear sir, for I learned it, according to the Oriental custom under the most sacred obligations of secrecy. One must advance through the whole course, by initiatory degrees, before learning the final mysteries of the samurais. Now, we have a working hypothesis. The girls could never have accomplished this. One man and one alone must have killed the three, although doubtless with confederates. Yamashino assured me that there were only six men in this country who knew it beside myself. We must find an Orientalist!”
Shirley paced the floor, but his meditations were interrupted by the arrival of the Coroner and his physician. Van Cleft hurried into the room with them, to present the doctor, who exchanged a formal greeting with the men he had met twice before that week.
“A sad affair, Professor,” observed the Coroner nervously, drinking in with profound respect the magnificent surroundings which symbolized the great wealth of which he secretly hoped to gain a tithing. “I trust that, as usual, in such cases, I may suggest an undertaker?”
“Why—talk about that at once, sir?” asked Howard with a shudder.
The physician, familiar with the subtleties of coroners, gently placed an arm about the young man's shoulder. He nodded, understandingly, to the Coroner, as he turned toward Shirley.
“I must be going now,” the latter interposed. “Just a word with you, Howard, that I may send a message to your mother and sister.”
The physician led away the two officials as Shirley continued: “I must go to see Cronin—deserted there like a run-over mongrel on the street. Can I leave this house by the rear, so that none shall know of my assistance in the case, or follow me to the hospital? If you can secure an old hat and coat, I will leave my own, with my stick, to get them some other time.”
“I will get some from the butler, if you wait just a moment. You can leave by the rear yard, if you don't mind climbing a high board fence.”
Van Cleft hurried downstairs, in a few minutes, bearing a weather-beaten overcoat and an English cap, which Shirley drew down over his ears. With the coat on, he looked very unlike the well-groomed club man who had entered. Unseen by Van Cleft he shifted an automatic revolver into the coat pocket from the discarded garment.
“Now, Mr. Shirley, come this way. Follow the rear area-way, across to the next yard, where after another climb you find a vacant lot where the Schuylers are preparing to erect their new city house. Will you attend to everything?”
