ten o'clock
Agatha was none the worse for her strange excursion , but I was nervous and unstrung , unable to listen to or answer the stream of comments which Wilson was pouring out for my benefit . As I bade her good-night Miss Penclosa slipped a piece of paper into my hand . `` Pray forgive me , '' said she , `` if I take means to overcome your scepticism . Open this note at ten o'clock to-morrow morning . It is a little private test . '' I ca n't imagine what she means , but there is the note , and it shall be opened as she directs . My head is aching , and I have written enough for to-night .
