How do you find a spy in a group of spies?

There’s a traitor in the ranks of MI5. The Director General is forced to find an outside investigator to conduct a search into his teams. Detective Chief Superintendent John Gaffney is in Special Branch, and with his previous experience and highly qualified mind, he is perfect for the job. With a small but select team, Gaffney is put in charge of the operation.
He plans an elaborate trap, designed to catch those who are usually the ones doing the catching.

Then, they hit a bump. One of the suspects commits suicide.

But is it suicide? With this group of highly trained suspects, anything is possible. Was it suicide, and therefore an admission of guilt? Or was someone trying to cover their own back?

Instead of being thrown off by this development, Gaffney uses this to his advantage. The uncertainty helps to bring some other evidence to light. Him and his team work their way through every fact and every piece of evidence until the truth finally comes to light.

In this exciting second Gaffney and Tipper Mystery, Graham Ison presents his readers with an intricate puzzle, only made better with his in-depth first-hand knowledge of working in Special Branch.

Graham Ison was born and brought up in Surrey where he still lives. The son of an artist, and grandson of a composer, he served in the army for five years before joining the police. After spending some time with the CID at Scotland Yard he transferred to the Diplomatic Protection Group and between 1967 and 1971 was Personal Protection Officer to Prime Ministers Harold Wilson and Edward Heath. In 1981 he moved back to Scotland Yard as Detective Chief Superintendent. He retired at this rank in 1986.
