Text message to Stense yesterday:
I think they're on to us. Initiate Protocol Delta-2 and rendezvous at the safe house. The codeword is FREMSLEY. P.B.A.B.
Stense's reply:
You are completely bonkers…
(You are completely bonkers is spook code-speak for message received and understood.)

Sounds as if the password has been compromised. Must tell Stense!
