Murder in the Museum

When Professor Julius Arnell breathes his last in the British Museum Reading Room it looks like death from natural causes. Who after all would have cause to murder a retired academic? Inspector Shelley's suspicions are aroused when he finds a packet of poisoned sugared almonds in the dead man's pocket; and a motive becomes clearer when he discovers Arnell's connection to a Texan oil millionaire. Soon another man plunges hundreds of feet into a reservoir on a Yorkshire moor. What can be the connection between two deaths? The mild-mannered museum visitor Henry Fairhurst adds his detective talents to Inspector Shelley's own and together they set about solving one of the most baffling cases Shelley has ever encountered.
