The Wind in the Willows Murder

In the early hours of the morning in a quiet Milton Keynes street, a single bullet was shot through an open window. The victim was a 19-year-old man. What followed was a frantic 999 call and an investigation by Thames Valley Police to find the culprit.

But it soon turns out there is more to the inquiry than meets the eye with a potential second suspect.
