It occurred to me that the best thing I could do while I was waiting was to lay in a stock of fresh provisions. I could hardly expect Campbell to subsist entirely upon a diet of dry biscuits and champagne, so summoning another taxi, I told the driver to take me to Fortnum and Mason's. Here I purchased a number of delicacies, including a couple of cold chickens and a fresh tongue. I gave instructions that they should be packed in a hamper and sent off to the cloak-room at Liverpool Street to await my arrival, and then, still having half an hour to spare, I strolled across to the Piccadilly Hotel and treated myself to a glass of sherry and two or three caviare sandwiches. At ten-thirty exactly I was back once more in Angel Court with my finger on the Inspector's bell. It had scarcely rung before the door was pulled open and the burly figure of Campbell himself appeared in the passage. "Glad to see you, Mr. Dryden," he exclaimed, giving me a hearty grip. "My clerk told me you'd be along in a minute. I'm sorry I wasn't in when you called before." "It was my fault," I said, following him into the office. "If people will come at such unholy hours they can hardly expect to find you at home." "We're used to early visitors in this line of business," he replied with a laugh. "Besides, you couldn't have come at a more convenient time anyhow. As a matter of fact I was just going to write to you." He pulled forward a tattered arm-chair, and, relieving me of my coat and hat, laid them on the sofa. "Are you busy this morning?" I asked. "Can you fix things so that we shan't be interrupted for at least a couple of hours?" He glanced at me sharply from under his bushy eyebrows. "I daresay I can if it's really essential. Do you mind waiting a minute while I speak to my clerk?" He stepped out into the passage and entered the opposite room. A minute later he returned, and, having shut the door behind him, took the chair opposite mine. "Now," he enquired genially, "what's the trouble?" I suppose that the task of listening to the most incredible stories is just part and parcel of a detective's business. Few men had probably had more experience in this line than Campbell himself, but as I began to speak I wondered in my own mind if he had ever encountered such a strange yarn as the one which I was about to unfold. Following the same course that I had adopted with Bobby, I once more described my first meeting with Christine and her uncle that sunny afternoon in Manaos Harbour. Then, step by step, and taking infinite pains to omit nothing which might be of the least significance, I laid bare the whole amazing train of incidents which had led up to my present visit.
