Catch the Stinger, Before It Stings You! - E R Pomeransky

When Henry Guthrie arrives in Cornwall, he's a man on a mission. A retired assassin for MI6, he has recently been released from prison, wrongly convicted for the murder of his girlfriend, Stella. During the year in prison he received a coded letter giving clues to the identity of the real killer.

The clues lead him to a local hospital, a bee farm, and an RAF base. There he discovers chemical weapons of mass destruction, sarin and VX. Chemical waste is also being dumped on the base and down local tin mines, but it is mainly being dropped on Somalia.

In a land of tin mines and fishing villages, will Guthrie find Stella's killer before the killer murders him?
