yourselves quite at home," our beautiful hostess said, and, as she spoke, she placed a box of cigars, newly opened, upon the table at my elbow. "I am sorry," she added, "that I must leave you now."
There was a curious expression in her eyes as she smiled down at us, an expression that later I came to know too well. Then, turning, she swept gracefully out of the room, closing the door behind her.
I looked across at Osborne. For some moments neither of us spoke. The mysterious house was still as death.
"Well, Jack," I said lightly, though somehow I felt uneasy, "what do you make of it, old man?"
"It is just as I thought," he answered, taking a cigar out of the box and beginning to trim it.
"How do you mean—'just as you thought'?" I asked, puzzled.
"Gastrell is an impostor, and—and that isn't his wife."
He did not speak again for some moments, being busily occupied in lighting his long cigar. Presently he leaned back, then blew a great cloud of smoke towards the ceiling.
Suddenly we heard a click, like the wooden lid of a box suddenly shut.
"Hullo!" he exclaimed suddenly, "what's that?"
"What's what?"
"Why! Look!" he gasped.
His gaze was set upon something in the shadow of a small table in a corner of the room—something on the floor. In silence, now, we both stood staring at it, for Osborne had risen suddenly. Slowly it moved. It was gradually gliding along the floor, with a sound like paper being pushed along a carpet. Whence it came, where it began and where it ended, we could not see, for the shadow it was in was very deep. Nor was its colour in the least discernible.
All we could make out was that some long, sinuous, apparently endless Thing was passing along the room, close to the wall farthest from us, coming from under the sofa and disappearing beneath the table.
All at once Osborne sprang towards me with an exclamation of alarm, and I felt his grip tighten upon my arm.
"Good God!" he cried.
An instant later a broad, flat head slowly reared itself from beneath the red table-cover which hung down almost to the floor, rose higher and higher until the black, beady, merciless eyes were set upon mine, and in that brief instant of supreme suspense my attention became riveted on the strange, slate-grey mark between and just behind the reptile's cruel eyes. Then, as its head suddenly shot back, Osborne dashed towards the door.
Once, twice, three times he pulled frantically at the handle with all his force.
"Good God! Berrington," he cried, his face blanched to the lips, "we're locked in!"
Almost as he spoke, the serpent with head extended swept forward towards us, along the floor.
I held my breath. Escape from its venomous fangs was impossible.
We had been trapped!
CHAPTER III
A HAMPSTEAD MYSTERY
With a shriek of alarm I leapt to the further side of the table which stood in the middle of the room, and at that moment hurried footsteps became audible.
Our wild shouts for help had evidently been heard, for someone was hurrying down the bare oak stairs into the hall.
"Hang this confounded lock—it catches!" we heard a voice exclaim as the handle turned. Then an instant later the door was flung open, and Gastrell stood before us.
"I am dreadfully sorry, you fellows," he said apologetically, "that you should have been alarmed in this way, because I can assure you that my tame cobra, 'Maharaja,' is quite harmless—look at him now," and we saw that the horrid reptile had swung round the instant its master had entered, and was sliding towards his feet. "He's a pet of mine—I brought him home with me, and he follows me like a dog—no, you needn't be in the least nervous," he added quickly, seeing that I instinctively edged away as the reptile passed. "I'm awfully sorry to have kept you waiting. I must apologize, too, for that confounded door—I myself got locked in here the other day. My wife told you I was out, but I was not. I came in by the side door, and she didn't know I was back, because I went straight upstairs. If you'll wait a moment I'll take our friend 'Maharaja' out."
He left the room, and the snake slid rapidly along the floor after him, almost, as he had said, like a dog following his steps.
"A nice cheerful pet to keep," I remarked, annoyed at my experience; but at that moment the mysterious Gastrell bustled in alone.
"So sorry," he said, and, after thanking us for coming out so far to ascertain if he had lost his purse, he pulled up a chair, seated himself between us, lit a big cigar, and helped us to whiskey from a silver tantalus.
"You had better add the soda yourselves," he said. "And now there is something I want to say to you both. You must have been surprised at my declaring so emphatically this evening that I had not met either of you before—eh?"
"I can answer for myself," Osborne exclaimed quickly. "Are you going to admit, after all, that you were on the Masonic?"
"Of course! Who else could it have been? Any more," he added, addressing me, than it could have been someone other than me whom you met in Geneva?"
"Then why did you deny it?" Osborne said rather irritably, looking hard at him with an expression of disapproval and mistrust, while my eyes wandered to that little gold medallion upon his chain.
"Because I had to,—that is, it was expedient that I should," was his reply. "I have a reason for not wanting it to be generally known that I am married,—least of all did I want Easterton, whose house I have just leased, to know me to be a married man; indeed, I told him some weeks ago that I was a bachelor—I had to, for reasons which I can't reveal at present."
He stopped speaking, and we watched him narrowly.
"Still," I remarked, "I don't see how you could have been on board ship in the middle of the ocean, and at the same time in London."
"I didn't say I was. I wasn't. I was in London a fortnight ago, and spent some hours with Lord Easterton. On the same day I sailed for Madeira, where I joined my wife on the homeward-bound Masonic. Think, Mr. Osborne," he ended, his curious gaze set on my companion's face, "think when we first met on board. It was not before the ship reached Madeira, surely."
Jack Osborne reflected.
"By Jove, no!" he suddenly exclaimed. "How odd I should all along have thought you had embarked at Capetown with the rest of us. But Mrs. Gastrell came from the Cape, surely?"
"She did, and the name 'Mr. Gastrell' was also in the passenger list, because a cousin of mine should have been on board. At the eleventh hour he was prevented from sailing, and it was upon receipt of a cable from him that I decided to catch the next boat to the Canaries and there meet my wife."
I admit that, as he paused, I felt rather "small"; and I believe Osborne felt the same. We had driven from the club right out here to Swiss Cottage, and on the way we had conjured up in our imaginations all sorts of mysterious happenings, even possible intrigues; and now the whole affair proved to have been "quite ordinary," with a few commonplace incidents to relieve its monotony—notably the incident of the giant cobra.
True, there was the mystery of the locked door. But then, had it really been locked? I had not myself tried to open it, and now as I thought about it, it seemed to me quite possible that Jack Osborne might, in the excitement of the moment, have failed to turn the handle sufficiently, and so have believed that the door was locked when it was not. Again we had Gastrell's assurance that he had found himself locked in one day. As for his declaration to Easterton that he was not the Gastrell whom Osborne had met on the Masonic, it was clear now that he had some secret reason for wishing to pass in London as a bachelor, and as Osborne had told Easterton that the Gastrell on the Masonic had told him that he had met me in Geneva, naturally Gastrell had been driven—in order to conceal his identity—to maintain that he had never before met me either.
Our host insisted upon our taking another of his very excellent cigars before we left,—it
