I believe it was Lorraine who sent the telegram.

I wrote to you as soon as I could after your father's death, but fainted just as I finished directing the letter.

I do not think he knows where your brother is, and, if possible, he must not know.

If you can by any means, _do_ send a letter to Harry and warn him not to attempt to come home.

I don't know how you will succeed, for Lorraine has us all under surveillance.
