My dear P.M.,

SECRECY OF CERTAIN DOCUMENTS

It has been pointed out to me that, whilst the secrecy of the
majority of documents depends on their freshness and evaporates
with time, there are others which are from their nature never to
be divulged. In the latter category comes such a document as W.7.,
which I send in this envelope, a comprehensive summary of what
measures the C.I.D. are taking to prepare for another war.
I was told the fact that quite a considerable personal
correspondence goes on continually between the Secretary of State
for India and the Viceroy. This correspondence is private and the
papers are the personal property of the Viceroy and, at his
discretion, are taken away or destroyed by him, on his successor
taking office.

Papers of importance sent out to you by me could, of course, at
your discretion, be so treated. [1]

I am, Yours very truly,
R. G. CASEY
