Bow at a Venture

When a body with no identity is found in an Edinburgh hotel Detective Chief Inspector Ian Forsyth is able to deduce that the body has not been killed in that room and find out the name of the dead man who was a faith healer. The wife of the healer is then murdered at a function to celebrate the life of the dead man. Finally another member of the faith healing entourage is murdered by being shot in the back with an arrow during an archery contest and is found with a Xmas light in his hand. D C Collins and the rest of the murder squad separately come up with two different solutions. But it is left to Forsyth to arrive by logical deduction at the one and only solution that explains all the anomalies why the last victim was killed in the way that he was and why he had the light bulb in his hand.
