Gently Where the Birds Are — Alan Hunter

The unflappable Inspector George Gently has become a household name through the hit BBC TV series starring Martin Shaw. These are the original books on which the TV series was based, although the George Gently in Alan Hunter's whodunits is somewhat different to his TV counterpart. He is more calculating, more analytical, and his investigations are even more enthralling.

In this title:

Who has been murdered? Where is the crime scene? Where is the body? All Gently has to go on is an anonymously delivered photograph of a corpse.
The photograph of the corpse, shot in the head and lying in a forest clearing, comes with no explanation or identification other than the East Anglian postmark on the envelope. The first thing that Gently has to find out is whether a crime has actually been committed.
Is it some kind of cruel hoax or has a hideous murder been committed at a woodland beauty spot? Exactly where is the crime scene, where is the body and who is the victim?
The camera never lies, but it seldom tells the whole truth, either.
