When Last I Died
When Last I Died is a 1941 mystery detective novel by the British writer Gladys Mitchell. It is the thirteenth in her long-running series featuring the psychoanalyst and amateur detective Mrs Bradley. In a review in The Observer, Maurice Richardson described it as "perhaps Miss Mitchell’s best, most ingenious crime story yet." Synopsis
After renting a house by the seaside Mrs Bradley comes across the diary of a former tenant in the house Bella Foxley, once accused of murdering her cousin some years before. Convinced that Bella was unfairly accused, Mrs Bradley takes it upon herself to investigate a supposedly haunted house where the murder has taken place. References
