It is 1935 and The Crime Guild of England are meeting up at the Hotel for their annual event to celebrate their love of detective fiction in an era which has become known as the Golden Age of the whodunit. The Guild members attending all have their favourite authors and their favourite fictional detectives: Writers such as Ngaio Marsh, John Dickson-Carr, Margery Allingham, Dorothy L Sayers and, of course, the Queen of Crime herself, Agatha Christie: Detectives such as Roderick Alleyn, Dr Gideon Fell, Lord Peter Wimsey, Miss Jane Marple, Mrs Bradley, and Tuppence Beresford.

They arrive for the evening in the guise of their chosen detective little knowing that a real tragedy will take place and that they will all be suspects in their own murder mystery.

 The evening starts happily enough but soon tensions mount and long held secrets are revealed. Eventually one of the members of the Guild is found dead, murdered, and it is down to one of the group to lead the investigation until the local police can get to the scene. The suspects are all seasoned murder mystery readers and could each have constructed a fiendishly devised plot to avoid detection. Equally, they would all consider themselves experts in solving fiendishly devised plots, so will the true motive come to light and will the killer, or killers, be caught?

All the clues will be there to lead to the right conclusion but will they be correctly deduced? The investigator, together with the help of the other guests staying at the hotel, must get to the truth before the weekend is out.
