"Granger?"
"The policeman, miss. Now I'm told they've sent for a doctor."
A second footman handed her an envelope as she entered the hall. She saw that "Oak Dene" was impressed in scarlet letters on the flap.
"When did this come?"
"One of Mr Morice's grooms brought it soon after you went out."
She tore the envelope open, and there and then read the note which it contained. It had no preamble, it simply ran,--
"Why have you not acted on my suggestion and gone back to Lake Como or farther?
"At any moment it may be too late! Don't you understand?
"When I think of what may be the consequences of delay I feel as if I were going mad. I shall go mad if you don't go. I don't believe that I have slept an hour since.
"Do as I tell you--go! H. M."
