Murder by Soup

It's 1980 and crime author Angelo Fox, creator of private eye Jimmy Finn has escaped the pressure of writing with a holiday to Corfu.
Dave Barton, an annoying guest in the hotel where Angelo is staying, is murdered. The hotel waiter is arrested as the main suspect after poison is found in Barton's soup.
Two elderly ladies at the hotel, fans of Angelo, who seem to know more about how Jimmy Finn works than Angelo himself, recognise him from his image on the back cover of one of his paperbacks. They are both convinced that the arrested waiter, Tobias, is so sweet and gentle that he must be innocent, and would Angelo investigate? "What would Jimmy Finn do?" they keep asking. At first Angelo is reluctant, but realising he'll get no peace he agrees to look into it.
His research digs up more than he bargained for, particularly a corrupt police chief, who is determined to stop Angelo's snooping. But Angelo has an array of allies on his side in the form of the two ladies, the hotel owner's sons, a geeky holiday rep and a band of unruly Club 18-30 holiday revellers.
