"I saw him in London about a month ago," I remarked, in order to sustain the fiction. How I longed to open that letter that lay so tantalisingly before me. But what could I do? Such a thing was not to be thought of. Therefore, I had to watch the woman gather the correspondence together and replace them in the cupboard. I rose and thanked her, saying,-- "I'm delighted to think that Charlie will escape a very disagreeable affair. It's fortunate he wasn't here to receive that letter." "And I'm glad, too. When he returns I'll tell him how you came here, and what you said. What name shall I give him?" "Williams--Harry Williams," I answered. "He will know." Then as I walked round to the window I examined the room quickly, but to my disappointment saw that there were no photographs.

In a moment it was in my pocket. I re-closed the cupboard, and sprang to the opposite side of the room just as the good woman re-entered. Then, with profuse thanks and leaving kind messages to the man of whom I spoke so familiarly as "Charlie," I took my leave and hurried along the broad road into Salford, where I jumped upon a tram going to the Exchange. I was in the train alone, in a third-class compartment, travelling north to Carlisle, before I dared to break open the letter. When I did so I found within a scribbled note in cipher written on the paper of the Bear Hotel, at Devizes. After some difficulty, with the aid of the key which the writer had evidently used in penning it, I deciphered it as follows:--
