are friends, and entrez nous, notorious for 
their peccadilloes. The girls must be in the vicious circle, and ably 
assisted. But there is one thing I forgot to tell you, which you forgot to 
ask." 
"And this is?" 
"How they died. It was by some curious method of sudden arterial 
stoppage. Old as they were, some fiendish trick was employed so 
skilfully that the result was actual heart failure. There was no trace of 
drugs in lungs or blood. On each man's breast, beneath the sternum 
bone I found a dull, barely discernible bruise mark, which I later 
removed by a simple massage of the spot!" 
Shirley closed his eyes, and passed his hand over his own chest --along 
the armpits--behind his ears--he seemed to be mentally enumerating 
some list of nerve centers. The physician observed him curiously. 
"I have it, doctor! The sen-si-yao!" 
"What do you mean?" 
"The most powerful and secret of all the death-strokes of the Japanese
art of jiu-jitsu fighting. I paid two thousand dollars to learn the course 
from a visiting instructor when I was in college. It was worth it for this 
one occasion." 
Shirley arose to his feet, and approached the other, touching his 
shoulder. 
"Stand up, if you please. Let me ask if this was the location of the 
mark?" 
The physician, interested in this new professional phase, readily obeyed. 
One quick movement of Shirley's muscular hand, the thumb oddly 
twisted and stiffened, and a sudden jab in the doctor's abdomen made 
that gentleman gasp with pain. Shirley's expression was triumphant, but 
the professor regarded him with an expression of terror. 
"Oh! Ugh!--What-did-you-do-to me?" he murmured thickly, when he 
was at last able to speak. 
"Merely demonstrated the beginning of the death punch which I named. 
That pressure if continued for half a minute would have been fatal." 
"I wish you would teach me that," was the physician's natural request, 
as he nodded with a wry face. 
"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?" 
"Everything. I'll start sooner than you expect." 
Truly he did! For no sooner had he descended the second fence into the
empty lot than a stinging blow sent him at full length on the rocky 
ground, where the excavations were already being started.
