Gently Floating [EPUB ebook] 

Gently wades through a torrent of suspects when a body is found floating face down in the river.Sometimes you can have too much of a good thing — that’s if you can call having too many suspects, too many potential murderers, ‘a good thing’. What Gently has to work out is which of them had the cold blooded nerve to smash the victim’s skull and dump him in the river.
