four
o'clock
I was led to expect that one of these visits would be paid on a certain day about a week ago , and I accordingly managed to be on the look-out in company with my cicerone at a quarter to ten , and the hour and the lady came with equal punctuality . My friend and I were standing under an archway , a little way back from the street , but she saw us , and gave me a glance that I shall be long in forgetting . That look was quite enough for me ; I knew Miss Raymond to be Mrs. Herbert ; as for Mrs. Beaumont she had quite gone out of my head . She went into the house , and I watched it till four o'clock , when she came out , and then I followed her . It was a long chase , and I had to be very careful to keep a long way in the background , and yet not lose sight of the woman . She took me down to the Strand , and then to Westminster , and then up St. James 's Street , and along Piccadilly . I felt queerish when I saw her turn up Ashley Street ; the thought that Mrs. Herbert was Mrs. Beaumont came into my mind , but it seemed too improbable to be true .
