“I’m sorry,” said Kerry. “You should always bang a door wide open suddenly before you enter into a suspected room. Anybody standing behind usually stops it with his head.”
“I am indebted for the hint, Chief Inspector. We all have something to learn.”
“Well, sir, we’ve laid our cards on the table, and you’ll admit we’ve both got a lot to learn before we see daylight. I’ll be obliged if you’ll put me wise to your game. I take it you began work on the very night of the murder?”
“I did. By a pure accident—the finding of an opiated cigarette in Mr. Gray’s rooms—I perceived that the business which had led to my recall from the East was involved in the Bond Street mystery. Frankly, Chief Inspector, I doubted at that time if it were possible for you and me to work together. I decided to work alone. A beard which I had worn in the East, for purposes of disguise, I shaved off; and because the skin was whiter where the hair had grown than elsewhere, I found it necessary after shaving to powder my face heavily. This accounts for the description given to you of a man with a pale face. Even now the coloring is irregular, as you may notice.
“Deciding to work anonymously, I went post haste to Lord Wrexhorough and made certain arrangements whereby I became known to the responsible authorities as 719. The explanation of these figures is a simple one. My name is Greville Seton. G is the seventh letter in the alphabet, and S the nineteenth; hence—‘seven-nineteen.’
“The increase of the drug traffic and the failure of the police to cope with it had led to the institution of a Home office inquiry, you see. It was suspected that the traffic was in the hands of orientals, and in looking about for a confidential agent to make certain inquiries my name cropped up. I was at that time employed by the Foreign office, but Lord Wrexborough borrowed me.” Seton smiled at his own expression. “Every facility was offered to me, as you know. And that my investigations led me to the same conclusion as your own, my presence as lessee of this room, in the person of John Smiles, seaman, sufficiently demonstrates.”
“H’m,” said Kerry, “and I take it your investigations have also led you to the conclusion that our hands are clean?”
Seton Pasha fixed his cool regard upon the speaker.
“Personally, I never doubted this, Chief Inspector,” he declared. “I believed, and I still believe, that the people who traffic in drugs are clever enough to keep in the good books of the local police. It is a case of clever camouflage, rather than corruption.”
“Ah,” snapped Kerry. “I was waiting to hear you mention it. So long as we know. I’m not a man that stands for being pointed at. I’ve got a boy at a good public school, but if ever he said he was ashamed of his father, the day he said it would be a day he’d never forget!”
