Just Cause: from the Diaries of Nicholas Hood

The UK has a killer in its midst but no ordinary killer. Victims are selected carefully and for a reason. Scotland Yard are alarmed and with no clues with four linked murders. Nicholas Hood is brought in. Although in his twilight years as a senior operative, this brash, arrogant and outspoken member of MI6 is probably the only man who can find the killer. Frequently direct and aggressive in conversation Nicholas quickly gets the establishment offside.
