The theory was plausible, but Inspector Whyland knew well enough that so far he had not a fragment of real evidence with which to support it. But, unless he were to adopt the suggestion of Mr. Ludgrove, that some homicidal maniac was responsible, Whyland could see no alternative. The lack of motive was so extraordinarily puzzling. The murders had been utterly purposeless, and the only possible theory could be one which took full account of this fact. And then again, how account for the despatch of the numbered counters? If the murders had been inspired by irresponsible impulse, what had been their object?
Still deep in thought, Inspector Whyland left the picture-house and walked slowly back to the police station through the less frequented streets. It was a little past eight on a typical December evening, with a light wet mist which magnified the outlines of the passersby and covered the pavements with a shining dampness. But the weather never had much effect upon Whyland, and, beyond a passing reflection that on such an evening murder in the streets of London was not, after all, an enterprise presenting any great difficulties to a determined man, he paid no great attention to it.
He reached the police station without adventure, ordered a modest supper, and sat down to deal with the mass of reports which awaited him. He was thus engaged when a sergeant entered the room, with the message that a man giving the name of Copperdock wished to speak to him on the telephone. He rose, walked to the instrument, and picked up the receiver. “Inspector Whyland speaking,” he said coldly.
“Is that you, Inspector?” came an excited voice, which Whyland recognized at once. “Can you come and see me at once? I’ve something very important to tell you.”
Whyland hesitated for a moment. Whatever it was that Mr. Copperdock had to say to him, a visit to his house could afford him an excellent opportunity for keeping his eyes open for some clue in support of his theory. “Yes, I’ll come along straight away,” he replied. With a word to the sergeant, he left the station and walked rapidly to Praed Street.
It was about a quarter to ten when he arrived and rang the bell outside Mr. Copperdock’s shop. The tobacconist was obviously awaiting him, and the door was opened immediately. With a brief word of greeting, Mr. Copperdock led the way upstairs to the sitting-room. Then, shutting the door carefully behind him, he turned dramatically, “I’ve seen that there black sailor!” he exclaimed in a hoarse whisper.
Inspector Whyland looked at him sharply. When the reward had originally been offered, he had been overwhelmed by a flood of people who had claimed to have seen the “black sailor,” but of late this elusive figure had ceased to occupy the popular imagination. Was this a vindication of his theory, showing that Mr. Copperdock’s brain was completely under the influence of the crime?
“You have seen the black sailor? Sit down and tell me all about it, Mr. Copperdock,” he replied gravely.
But Mr. Copperdock was far too excited to sit down. “I see him plain as I see you now,” he exclaimed. “Just after I left the Cambridge Arms—”
But Inspector Whyland put out his hand and forced him gently into the nearest chair. “Now, look here, Mr. Copperdock, if your information is to be of any use to me, you must tell it to me in the proper order. Begin by telling me how you spent the evening.”
“Soon as I shut up shop at eight o’clock, I goes off to the Cambridge, same as I always does,” replied the tobacconist protestingly. “Ted went out too, he’s taking Ivy to the pictures, and they won’t be back for an hour or so yet. I has a couple there, sitting in front of the fire, and it wasn’t until nigh on closing time that I left. There wasn’t anybody there as was coming home my way, so I starts off home alone. And I hadn’t gone more than a hundred yards when I runs slap into the black sailor!”
“What do you mean when you say you ran into him?” interrupted Whyland.
“Just what I says. I saw someone come round the corner, and before I could move we ran into one another. He was a great big fellow, and I could see him perfectly plain, we was right under the lamp. He bent down and looked straight at me, and you could have knocked me down with a feather. It was the black sailor, all right. He was muffled up in a great heavy coat, but I could see his beard, and his woollen cap, and a great red scar down the right side of his face. He glared at me as though he were going to hit me, and I hollered out, being sure he was going to do me in. Then all at once he turns his back and walks off at a tremendous pace. After a bit I follows him, hoping to meet a copper. But he suddenly turns in to the Edgware Road, and by the time I gets there I’d lost him.”
“H’m,” said Inspector Whyland. “That must have been nearly an hour ago now.” He paused for a moment, then, realizing that in Mr. Copperdock’s present excited state it would be impossible to get anything coherent out of him, he rose and took his leave.
“Well, good night, Mr. Copperdock,” he said abruptly. “It’s a pity you didn’t catch your man. I’d better get back to the station and warn my people to look out for him.”
As he left the shop, he noticed that Mr. Ludgrove’s door stood open, and as he crossed the road, the herbalist himself
