Behind me came Rayner to see, as he swiftly put it, "that no harm came" to me.
The old man in the full enjoyment of his cigar, and apparently quite happy that if his offices were watched his two confederates would have taken off the watchers, strolled along St. Bride Street as far as the corner of Ludgate Hill, when he hailed a taxi and drove westward. His example I quickly followed, leaving Rayner standing on the kerb, unable to follow, as no third cab was in sight.
Up Fleet Street we drove quickly and along the Strand as far as Charing Cross, when the taxi I was pursuing turned into Northumberland Avenue and pulled up before the Hôtel Metropole.
I drew up further along, at the corner of the Embankment, at the same time watching the old man pay the driver and enter, being saluted by the uniformed porter, who evidently knew him.
For about five minutes I waited. Then I entered the hotel, where I also was well known, having very often stayed there.
Of the porter at the door, who touched his hat as I went in, I asked the name of the old gentleman who had just entered.
"I don't know his name, sir. He often stays here. They'll tell you at the key-office."
So I ascended the stairs into the hall, and made inquiry of the sharp-eyed, dark-faced man at the key-counter.
"Oh, Mr. Vernon, you mean, sir? Been in about five minutes. He's just gone up in the lift – Room 139a, first-floor – shall I send your name up, Mr. Vidal?"
"No, I'll go up," I said. "You're sure he is up in his room?"
"Quite sure, sir. He took his key about five minutes ago."
"Is he often here?"
"Every month," was the reply. "He usually spends about a week with us, and always has the same room."
"What is he? Have you any idea?"
"I've heard that he's a diamond-broker. Lives in Paris, I fancy."
"Has he many callers?"
"One or two business men sometimes; but only one lady."
"A lady!" I echoed. "Who?"
"Oh, a very pretty young French girl who comes sometimes to see him," replied the clerk. Then, after reflection, he added: "I think the name is Sorel – Mademoiselle Sorel."
I started at mention of the name.
"Does she come alone?" I asked. "Excuse me making these inquiries," I added apologetically, "but I have strong reasons for doing so."
"Once she came alone, I think about six weeks ago. But she generally comes with a tall, rather ugly, but well-dressed Frenchman of about forty-five, a man who seems to be Mr. Vernon's most intimate friend."
I asked for a further description of her companion, and decided that it was Jules Jeanjean.
"Is the hotel detective about?" I asked.
"Yes. He's somewhere down on the smoking-room floor. Do you want him?" he asked, surprised.
I replied in the affirmative. Whereupon a page was at once dispatched, and returned with an insignificant-looking man, an ex-sergeant of Scotland Yard, engaged by the hotel as its private inquiry agent.
He knew me well, therefore I said —
"Will you come up with me to 139a. I want to see a Mr. Vernon, and there may be a little trouble. I may have to call in the police."
"What's the trouble, sir?" he asked in surprise, though he knew me to be an investigator of crime.
"Only a little difference between us," I said. "He may have a revolver. Have you got one?"
The detective smiled, and produced a serviceable-looking Colt from his hip-pocket, while I drew a long, plated, hammerless Smith & Wesson, which has been my constant companion throughout my adventurous life.
Then together we ascended in the lift, and passed along the corridor till we found the room which the clerk had indicated.
I tapped loudly at the door, at the same moment summoning all my self-possession. I was about to secure one of the most cunning and clever criminals on earth.
There was no answer. Yet I distinctly heard some one within the room.
Again I knocked loudly.
Then I heard footsteps advancing to the door, which was thrown open, and a chambermaid stood there.
"I'm sorry, sir," she said apologetically.
I drew back in dismay.
"Is Mr. Vernon in here?" I asked breathlessly.
"Mr. Vernon – the gentleman in this room, sir?"
"Yes. He has come up here, I know."
"He did come in a few minutes ago, and took a small leather case, but he went out again at once."
"Went out? You saw him?"
"Yes. He was coming out just as I came in, sir," replied the girl.
"Gone!" I gasped, turning to the ex-sergeant.
"He must have gone down the stairs, sir," the man suggested.
With a glance round the room, which only contained a suit-case, I dashed down the stairs and into the hall.
Of the porter at the door I asked a quick question.
"No, sir," he replied. "Mr. Vernon hasn't gone out this way. He may have gone out by the door in Whitehall Place."
I rushed through the hotel and, at the door indicated, the man in uniform told me that Mr. Vernon had left on foot five minutes before, going towards Whitehall.
