She smiled very prettily at this, and again we walked on for a while up the slope without speaking. Once she turned her head as if listening for some sound from behind us, but our feet were making so much noise on the loose gravel, and the sound reverberated so much in the narrow space between the wooden fences that I, at least, heard nothing. Presently we turned a slight bend and came in sight of the opening at the top of the hill, guarded by a couple of posts. Within a few yards of the latter she halted, and withdrawing her hand from my arm, turned round and faced me. "We must say 'Good-bye' here," said she. "I wonder if I shall ever see you again."
For a moment I felt a strong impulse to propose some future meeting at a definite date, but fortunately some glimmering of discretion—and perhaps some thought of Sylvia—restrained me. "Why shouldn't you?" I asked.
"I don't know. But mine is rather a vagabond existence, and I suppose you will be travelling about I hope we shall meet again soon; but if we do not, I shall always think of you as my friend, and you will have a kind thought for me sometimes, won't you?"
"I shall indeed. I shall think of you very often and hope that your life is brighter than it seems to be now."
"Thank you," she said earnestly; "and now 'Good-bye!'"
She held out her hand, and, as I grasped it, she looked in my face with the wistful, yearning expression that I had noticed before, and which so touched me to the heart that, yielding to a sudden impulse, I drew her to me and kissed her. Dim as was the light of the fading winter's day, I could see that she had, in an instant, turned scarlet. But she was not angry; for, as she drew away from me, shyly and almost reluctantly, she gave me one of her prettiest smiles and whispered "Good-bye" again. Then she ran out between the posts, and, turning once again—and still as red as a peony—waved me a last farewell.
I stood in the narrow entrance looking out after her with a strange mixture of emotions; pity, wonder and admiration and a little doubt as to my own part in the late transaction. For I had never before kissed a married woman, and cooling judgment did not altogether approve the new departure; for if Mr. Samway was not all that he might be, still he was Mr. Samway and I wasn't. Nevertheless, I stood and watched my late companion with very warm interest until she faded into the dusk; and even then I continued to stand by the posts, gazing out into the waning twilight and cogitating on our rather strange interview.
Suddenly my ear caught a sound from behind me, down the lane; a sound which, while it set my suspicion on the alert, brought a broad grin to my face. It was what I suppose I must call a stealthy footstep, but the stealthiness might have stood for the very type and essence of futility, for, as I have said, the ground sloped pretty steeply and was covered with loose pebbles, whereby every movement of the foot was rendered as audible as a thunderclap. However, absurd as the situation seemed—if the unseen person was really trying to approach by stealth—it was necessary to be on my guard. Moreover, if this should chance to be the person with the nystagmus, the present seemed to be an excellent opportunity for coming to some sort of understanding with him.
Accordingly I wheeled about and began to walk back down the lane. Instantly, the steps—no longer stealthy—began to retire. I quickened my pace; the unknown and invisible eavesdropper quickened his. Then I broke into a run, and so did he, notwithstanding which, I think I should have had him but for an untoward accident. The ground was not only sloping, but, under the loose gravel, was as hard as stone.
Consequently, the foothold was none of the best, as I presently discovered, for, as I raced down one of the steepest slopes, the pebbles suddenly rolled away under my foot and I lost my balance. But I did not fall instantly. Half recovering, I flew forward, clawing the air, stamping, staggering, kicking up the gravel, and making the most infernal hubbub and clatter, before I finally subsided into a sitting posture on the pebbles. When I rose, the footsteps were no longer audible, though the lower end of the lane was still some distance away.
I resumed my progress at a more sedate pace and kept a sharp look-out for a possible ambush, though the lane was too narrow, even in the darkness that now pervaded it, to furnish much cover to an enemy. Some distance down, I came to an opening in the fence, where one or two boards had become loose, and was half disposed to squeeze through and explore. But I did not, for, on reflection, it occurred to me that if the man was not there it would be useless for me to go, while if he should be hiding behind the fence it would be simply insane of me to put my head through the hole.
When I emerged into the road at the bottom, I looked about vaguely, but, of course there was no sign of the fugitive—nor, indeed, could I have identified him if I had met him. I loitered about undecidedly for a minute or two, and then, realizing the futility of keeping a watch on the entrance of the lane for a man whom I could not recognize, and becoming conscious of a ravenous desire for food I made my way down the Grove in the direction of my lodgings.
XV. Exit Dr. Jardine
My second visit to "The Hawthorns," to which I had looked forward with some eagerness, had, after all, to be postponed indefinitely. I say "had," since, under the circumstances, it appeared to be so unsafe that I could not fairly take the risk that it involved. I had made the engagement thoughtlessly, and, in my preoccupation with Mrs. Samway, had not realized the indiscretion to which I had committed myself until I was brought back sharply to the actual conditions by the incident in Love Lane which I have mentioned. But, after that, I saw that it would be the wildest folly to show myself in the vicinity of Sylvia's house. Evidently the spy, after we had given him the slip so neatly, had made direct for my lodgings and lurked in the neighbourhood, and there it must have been that he had picked me up again as I passed with Mrs. Samway. Of course it was possible that the unseen person in the lane was not really shadowing me at all; but his stealthy approach, his hasty retreat and his mysterious disappearance, left me in very little doubt on the subject.
I was not very nervous about this enigmatical person on my own account. In spite of my alarming experiences, I found it difficult to take him as seriously as I should have done, and still felt a quite unjustifiable confidence in my capability of taking care of myself. But on Sylvia's account I was exceedingly uneasy. The interest that this man had shown in the unlucky little ornament that she wore, associated itself in my mind most disagreeably with her mysterious and terrifying adventure in Millfield Lane, and made me feel that it would be sheer insanity for me to go from my house to hers and so possibly give this unknown villain the clue to her whereabouts.
This conclusion, at which I had arrived overnight, was confirmed on the following morning, for, having taken a brisk walk out in the direction of Harrow, and having kept a very sharp look-out, I was distinctly conscious of the fact that there always appeared to be a man in sight. I never got near him and was not able to recognize him, but at intervals throughout the morning he continually reappeared in the distance, even on the comparatively solitary country roads and the hedge-divided meadows.
It was excessively irritating. Yet what could I do? Even if I could have identified him with the man who had apparently shadowed me before, I really had nothing against him. And cogitating on the matter, with no little annoyance, I determined to take counsel with Thorndyke, and meanwhile to avoid the neighbourhood of "The Hawthorns."
After lunch, I wrote a letter to Sylvia, briefly explaining the state of affairs, and, having given it to our maid to deliver, I took the precaution to go out and saunter towards Kentish Town with the object of engaging the spy's attention and preventing him from following my messenger to North End. The rest of the day I spent at home and occupied my time in writing a long letter to Thorndyke in which I gave a pretty detailed account of my recent experiences; which letter was duly posted by Mrs. Blunt herself in time for the evening collection.
I had barely seated myself at the breakfast table on the following morning when a telegram was brought to me. On opening it I found that it was from Thorndyke, advising me that a letter had been dispatched by hand and
