Craig took the shell which O'Connor drew from another pocket and trying to fit the bullet and the cartridge together remarked "both from a .44, probably one of those old-fashioned, long-barrelled makes."
"There," concluded O'Connor ruefully, "you know all we know of the thing so far."
"I may keep these for the present?" inquired Kennedy, preparing to pocket the shell and the bullet, and from his very manner I could see that as a matter of fact he already knew a great deal more about the case than the police. "Take us down to this old house and dock, if you please."
Over and over, Craig paced up and down the dilapidated dock, his keen eyes fastened to the ground, seeking some clue, anything that would point to the marauders. Real persons they certainly were, and not any ghostly crew of the bygone days of harbour pirates, for there was every evidence of Borne one who had gone up and down the walk recently, not once but many times.
Suddenly Kennedy stumbled over what looked like a sardine tin can, except that it had no label or trace of one. It was lying in the thick long matted grass by the side of the walk as if it had tumbled there and had been left unnoticed.
Yet there was nothing so very remarkable about it in itself. Tin cans were lying all about, those marks of decadent civilisation. But to Craig it had instantly presented an idea. It was a new can. The others were rusted.
He had pried off the lid and inside was a blackish, viscous mass.
"Smoking opium," Craig said at last.
We retraced our steps pondering on the significance of the discovery.
O'Connor had had men out endeavouring all day to get a clue to the motor car that had been mentioned in some of the accounts given by the natives. So far the best he had been able to find was a report of a large red touring car which crossed from New York on a late ferry. In it were a man and a girl as well as a chauffeur who wore goggles and a cap pulled down over his head so that he was practically unrecognisable. The girl might have been Miss Curtis and, as for the man, it might have been Clendenin. No one had bothered much with them; no one had taken their number; no one had paid any attention where they went after the ferry landed. In fact, there would have been no significance to the report if it had not been learned that early in the morning on the first ferry from the lower end of the island to New Jersey a large red touring car answering about the same description had crossed, with a single man and driver but no woman.
"I should like to watch here with you to-night, O'Connor," said Craig as we parted. "Meet us here. In the meantime I shall call on Jameson with his well-known newspaper connections in the white light district," here he gave me a half facetious wink, "to see what he can do toward getting me admitted to this gilded palace of dope up there on Forty-fourth Street."
After no little trouble Kennedy and I discovered our "hop joint" and were admitted by Nichi Moto, of whom we had heard. Kennedy gave me a final injunction to watch but to be very careful not to seem to watch.
Nichi Moto with an eye to business and not to our absorbing more than enough to whet our descriptive powers quickly conducted us into a large room where, on single bamboo couches or bunks, rather tastefully made, perhaps half a dozen habitué's lay stretched at full length smoking their pipes in peace, or preparing them in great expectation from the implements on the trays before them.
Kennedy relieved me of the responsibility of cooking the opium by doing it for both of us and, incidentally, dropping a hint not to inhale it and to breathe as little of it as possible. Even then it made me feel badly, though he must have contrived in some way to get even less of the stuff than I. A couple of pipes, and Kennedy beckoned to Nichi.
"Where is Mr. Clendenin?" he asked familiarly. "I haven't seen him yet."
The Japanese smiled his engaging smile. "Not know," was all he said, and yet I knew the fellow at least knew better English, if not more facts.
Kennedy had about started on our faking a third "pipe" when a new, unexpected arrival beckoned excitedly to Nichi. I could not catch all that was said but two words that I did catch were "the boss" and "hop toy," the latter the word for opium. No sooner had the man disappeared without joining the smokers than Nichi seemed to grow very restless and anxious. Evidently he had received orders to do something. He seemed anxious to close the place and get away. I thought that some one might have given a tip that the place was to be raided, but Kennedy, who had been closer, had overheard more than I had and among other things he had caught the word, "meet him at the same place."
It was not long before we were all politely hustled out.
"At least we know this," commented Kennedy, as I congratulated myself on our fortunate escape, "Clendenin was not there, and there is something doing to-night, for he has sent for Nichi."
We dropped into our apartment to freshen up a bit against the long vigil that we knew was coming that night. To our surprise Walker Curtis had left a message that he wished to see Kennedy immediately and alone, and although I was not present I give the substance of what he said. It seemed that he had not wished to tell O'Connor for fear that it would get into the papers and cause an even greater scandal, but it had come to his knowledge a few days before the tragedy that his sister was determined to marry a very wealthy Chinese merchant, an importer of tea, named Chin Jung. Whether or not this had any bearing on the case he did not know. He thought it had, because for a long time, both when she was on the stage and later, Clendenin had had a great influence over her and had watched with a jealous eye the advances of every one else. Curtis was especially bitter against Clendenin.
As Kennedy related the conversation to me on our way over to Staten Island I tried to piece the thing together, but like one of the famous Chinese puzzles, it would not come out. I had to admit the possibility that it was Clendenin who might have quarrelled over her attachment to Chin Jung, even though I have never yet been able to understand what the fascination is that some Orientals have over certain American girls.
All that night we watched patiently from a vantage point of an old shed near both the house and the decayed pier. It was weird in the extreme, especially as we had no idea what might happen if we had success and saw something. But there was no reward for our patience. Absolutely nothing happened. It was as though they knew, whoever they were, that we were there. During the hours that passed O'Connor whiled away the time in a subdued whisper now and then in telling us of his experiences in Chinatown which he was now engaged in trying to clean up. From Chinatown, its dens, its gamblers and its tongs we drifted to the legitimate business interests there, and I, at least, was surprised to find that there were some of the merchants for whom even O'Connor had a great deal of respect. Kennedy evidently did not wish to violate in any way the confidence of Walker Curtis, and mention of the name of Chin Jung, but by a judicious question as to who the best men were in the Celestial settlement he did get a list of half a dozen or so from O'Connor. Chin Jung was well up in the list. However, the night wore away and still nothing happened.
It was in the middle of the morning when we were taking a snatch of sleep in our own rooms uptown that the telephone began to ring insistently. Kennedy, who was resting, I verily believe, merely out of consideration for my own human frailties, was at the receiver in an instant. It proved to be O'Connor. He had just gone back to his office at headquarters and there he had found a report of another murder.
"Who is it?" asked Kennedy, "and why do you connect it with this case?"
O'Connor's answer must have been a poser, judging from the look of surprise on Craig's face. "The Jap—Nichi Moto?" he repeated. "And it is the same sort of non-fatal wound, the same evidence of asphyxia, the same circumstances, even down to the red car reported by residents in the neighbourhood."
Nothing further happened that day except this thickening of the plot by the murder of the peculiar-acting Nichi. We saw his body and it was as O'Connor said.
"That
