I'm doing some research into my dad's life in WWII and have irrefutable proof that he was recruited by MI6. The documents I have seem to have been kept in order to prove what he did and where he went. Amongst them is a letter dated 14 Sept 1944 from Room 900 of the War Office saying that they were no longer able to retain his services (post invasion). Next in chronological order is a receipt from Post Office Savings Bank confirming a deposit of Â£270 into his account - dated 28th Sept 1944. Taking inflation into account, that equates to approx Â£6400. Is it common knowledge that MI6 agents were paid for services rendered?
