The interview left Sherlock Holmes very thoughtful, and several times in the next few days I saw him take his slip of paper from his notebook and look long and earnestly at the curious figures inscribed upon it. He made no allusion to the affair, however, until one afternoon a fortnight or so later. I was going out when he called me back.

“You had better stay here, Watson.”

“Why?”

“Because I had a wire from Hilton Cubitt this morning. You remember Hilton Cubitt, of the dancing men? He was to reach Liverpool Street at one-twenty. He may be here at any moment. I gather from his wire that there have been some new incidents of importance.”

We had not long to wait, for our Norfolk squire came straight from the station as fast as a hansom could bring him. He was looking worried and depressed, with tired eyes and a lined forehead.
