"Any answer, sir?" inquired the boy, when he saw I had finished reading.

"Yes, Charles," I said; "there is an answer, but I'm afraid I can't send it by post. Wait a minute, though," I added, as he began to put on his cap, "I want you to send off a wire for me if you will. It will take a minute or two to write."

I went into the hut, and hastily scribbled a telegram to Latimer, telling him that I had written to McMurtrie, but that otherwise there was nothing to report. I copied this out carefully in the simple cypher we had agreed on, and handed it to the boy, together with five shillings.

"You can keep the change," I said, "and buy fireworks with it. I've been too busy to make any yet."

He gurgled out some expressions of gratitude and took his departure, while I renewed my attack upon the sardines and bread.

Fortified by this simple cheer, I devoted the remainder of the morning to tidying up my shed. I felt that I was living in such uncertain times that it would be just as well to remove all possible traces of the work I had been engaged on, and by midday the place looked almost as tidy as when I had first entered it.

I then treated myself to a cigar and began to keep a look-out for
Joyce. She had not said in her letter what time she would arrive, but
I knew that there were a couple of trains early in the afternoon, and
I remembered that I had told her to come straight to the hut.

It must have been getting on for two when I suddenly caught sight of a motor car with a solitary occupant coming quickly along the Tilbury road. It pulled up as it reached the straggling plantation opposite the hut, and a minute later a girl appeared from between the trees, and started to walk towards me across the marsh.

I was a little surprised, for I didn't know that Joyce included motor driving amongst her other accomplishments, and she had certainly never mentioned to me that there was any chance of her coming down in a car. Then, a moment later, the truth suddenly hit me with paralysing abruptness. It was not Joyce at all; it was Sonia.

I don't know why the discovery should have given me such a shock, for in a way I had been expecting her to turn up any time. Still a shock it undoubtedly did give me, and for a second or so I stood there staring stupidly at her like a man who has suddenly lost the use of his limbs. Then, pulling myself together, I turned away from the window and strode to the door.
