"She might have found out who Murbles was. The advertisement which started the whole business was in his name, you know."
"In that case, why hasn't she attacked Murbles or you?"
"Murbles is a wise old bird. In vain are nets spread in his sight. He is seeing no female clients, answering no invitations, and never goes out without an escort."
"I didn't know he took it so seriously."
"Oh, yes. Murbles is old enough to have learnt the value of his own skin."
(from Unnatural Death, by Dorothy L. Sayers)
