Title: The Two Graphs
Description: Fiftieth in the long-running mystery series with Dr Launcelot Priestley.

 
>In the Norfolk Broads one of identical twin brothers drowns in a boating trip tragedy. From the second the survivor plans to step quietly into the shoes (and wealth) of his unfortunate sibling, events take a decidedly dangerous turn.

>It emerges that far from being the respectable citizen everyone thought, his brother was involved in some extremely dubious enterprises. The survivor attempts to hide himself away at a rest home where his brother had stayed the previous year - but this proves unsuccessful in shielding him from danger.

>The suspicions of the doctor who runs the home give Superintendent Waghorn the first clue he needs to begin to unravel the case – as well as providing the `two graphs' of the title – and with Priestley's help he manages to track the criminal.
