The cab returned to the stable, I locked the door, and by the light of one of the lamps, shaved off my beard and moustache. My uniform and cap I hung up on the hook where I usually left them after working hours, and changed into the suit which I had placed there in readiness. I next destroyed all evidences of identity and left the place in a neat condition. I extinguished the lamp, went out and locked the door behind me, and carrying a travelling-grip and a cane I set off for my new hotel.

Charles Malet had disappeared!

CHAPTER IV

I MEET AN OLD ACQUAINTANCE

On the corner opposite Dr. Stuart's establishment stood a house which was "to be let or sold." From the estate-agent whose name appeared upon the notice-board I obtained the keys—and had a duplicate made of that which opened the front door. It was a simple matter, and the locksmith returned both keys to me within an hour. I informed the agent that the house would not suit me.

Nevertheless, having bolted the door, in order that prospective purchasers might not surprise me, I "camped out" in an upper room all day, watching from behind the screen of trees all who came to the house of Dr. Stuart. Dusk found me still at my post, armed with a pair of good binoculars. Every patient who presented himself I scrutinized carefully, and finding as the darkness grew that it became increasingly difficult to discern the features of visitors, I descended to the front garden and resumed my watch from the lower branches of a tree which stood some twenty feet from the roadway.

At selected intervals I crept from my post and surveyed the lane upon which the window of the consulting-room opened and also the path leading to the tradesmen's entrance, from which one might look across the lawn and in at the open study windows. It was during one of these tours of inspection and whilst I was actually peering through a gap in the hedge, that I heard the telephone bell. Dr. Stuart was in the study and I heard him speaking.

I gathered that his services were required immediately at some institution in the neighbourhood. I saw him take his hat, stick and bag from the sofa and go out of the room. Then I returned to the front garden of my vacant house.

No one appeared for some time. A policeman walked slowly up the road, and flashed his lantern in at the gate of the house I had commandeered. His footsteps died away. Then, faintly, I heard the hum of a powerful motor. I held my breath. The approaching car turned into the road at a point above me to the right, came nearer … and stopped before Dr. Stuart's door.

I focussed my binoculars upon the chauffeur.
