Half-Mast for the Deemster — George Bellairs

Inspector Littlejohn is drawn into a perplexing case when a judge is murdered on the Isle of Man in this classic British mystery.

The small community of Castletown has plenty of odd customs -- one being the office of Deemster, who serves as every sort of judge rolled into one. When Inspector Littlejohn arrives on the island for a sporting holiday, this particular custom is brought to his attention with the utmost urgency . . . because Deemster Quantrell has just been killed.

The local police are glad to have the hotshot from Scotland Yard take the lead on such a perplexing case. Though the deemster was beloved by all, someone went to great lengths to poison him with cyanide in his private lunch room. As the investigation uncovers dark secrets and hidden crimes, other victims meet their end. And Littlejohn must act fast before a ruthless killer strikes again.
