a quarter
past eleven
To-night I locked up my flat at six o'clock . It was then , I am sure , empty . I dined with a friend and went to the ` Unusual . ' At a quarter past eleven I returned here with this gentleman , Mr. Brendon . As we turned the corner of the street , I noticed that the electric light was burning in this room . We stopped for a moment to watch it , and almost immediately it was turned out . We came on here at once .
