"But how do you know she was waiting to go on the barge?" I persisted.

"Why, I 'eard 'er call out, and I seed the doctor comin' orf to fetch 'er. I reckon she's there now—that's to say, if 'e ain't put 'er ashore again."

I said nothing further, but walked on to the boat in anything but a happy state of mind. The thought of Christine boxed up alone in the fog with those two scoundrels filled me with a horrible sense of uneasiness. Knowing her mistrust for Manning, and having seen something of the relations between them, I felt that only the strongest reasons would have induced her to take such a step.

It was possible, of course, that she had explained her action in the letter which she had given to Jimmy. If that were the case, the quicker I got back to the house the sooner my anxiety would be relieved, so without wasting any time I unshipped the oars and started off on my journey down the creek.

The tide was slack when we reached the mouth; and trusting to luck, for one could see only a few feet ahead, I cut straight across the estuary, and came out triumphantly almost exactly alongside the landing-stage.

Before stepping ashore I handed Jimmy a well-earned ten bob in return for his services. Then, with my bag in my hand, I strode forward through the mist and entered the narrow path which ran up through the shrubbery to the garden.

As I crossed the lawn and approached the house I noticed with some surprise that the front door was standing open. I was just thinking that it was rather unlike Bascomb to be so casual when I suddenly heard the sound of footsteps coming round the corner of the drive. I pulled up where I was, and the next moment the square, burly figure of my retainer loomed into view.

I was about to make some remark, but, whatever it was, the words remained unspoken. One glance at Bascomb's face was quite sufficient to drive everything else clean out of my head.

"Good God!" I exclaimed. "What's the matter?"

He stood there, glaring at me with sullen, blood-shot eyes—a silent and menacing figure in the mist. Then, taking a step forward, he laid his hand on my arm.
