I had got as far as this in my meditations when it suddenly struck me I was becoming maudlin. Also, there could be no doubt that I was as sleepy as an owl.

I got up with a laugh and a yawn, and, turning on the light, went into my bedroom.

It was a large apartment, even bigger than the sitting-room, and the magnificent four-poster bed was in keeping with its spaciousness. I made a tour of inspection, satisfying myself that there were no more charming ladies or visitors of any kind lying in wait for me, and then, carefully locking both the door of the room and the door into the study, I proceeded to take off my clothes and array myself in Northcote's silk pyjamas, which the faithful Milford had put out for me.

My last act was the result of a sudden inspiration. Before getting into bed, I crossed to the window and looked out very cautiously through a crack in the Venetian blind. Just as I did so, the dark figure of a man rose out of the shadow of the trees opposite and walked quickly down the roadway.

I got into bed and turned off the light.

"I wonder," I said to myself, "if that could have been Señor Guarez."

Five minutes later I was sound asleep.

CHAPTER V

Considering the amount of brandy that I had consumed, I awoke next morning feeling remarkably well. The first thing that met my eyes was the canopy of the bed. I stared at it in a kind of vague surprise, wondering how on earth it had got there. Then, with a sudden shock, the events of the previous evening came racing back into my mind. I realised that I was in Northcote's bedroom, and that someone was knocking gently but persistently at the door.
