I am not reading the Fethering series of books in any order and of all the ones I have read this is definitely a very good one - and a good place to start if you have never read any of Simon Brett's books before. My review assumes you enough though about the series main protagonists Carole and Jude and the local area, based in the West Sussex area, Worthing, Arundel to name a few.
Jude helps out at a prestigious local hotel owned by a long term friend, Suzy Longthorne. Through this friendship a bit more background is filled in about the mysterious Jude.
As Jude locks up the hotel for the night, she discovers one of that evenings dinner guests, has not quite made it to his bedroom. Jude being who she is helps Nigel Ackford into his room and bed. Only for the next morning to discover him hanging from the bed.
Everything points to suicide, but there is so many alibis and information flying about that it becomes difficult for Jude and obviously Carole (enlisted to help naturally!) to know the truth from the lies.
Simon Brett really has a good story here; with plenty of traditional detective story "red herrings" and characters not necessarily what they seem. One of the better Fethering Mysteries and well worth a read.
