report from Agent H17/E/4938765/i/ECK
I have now spent 17 days in the Willesden stake-out. I shall be glad
to get back to beans on toast again.
It is clear that Greenback is communicating with the underworld through
an ingenious and coplicated code. He places messages in an ordinary domestic
container outside the door of his HQ and theses are collected by a messenger
in the early hours of each morning.
The trained goldfish provideed by control has failed to return from
a retrieval mission across Willesden Green High Street. However, i succeeded
in photographing three of theses secret messages by disguising myself
as a garden path and after treatment for an attack of gravel, I dispatched
these yesterday to Major CXkkp3N, Head of Ciphers.
Must finish. Suspect am being watched. Reason to believe that Greenbackis
none other than..... aagh!
