A murder mystery set in Norfolk with half a dozen murders, three arrests, two trials with subsequent hangings (Good Reads).

Death Walks in Eastrepps begins quietly - almost too quietly. Robert Eldridge is returning to Eastrepps on the London train for his customary Wednesday-night tryst with Margaret Withers. At the same time Miss Mary Hewitt is sitting down to dinner with her brother James. Later that night she will make her usual visit to Mrs. Dampier at Tamarisk House. As she leaves to go home, nothing is out of the ordinary. But Mary Hewitt doesn't reach home that night, and her corpse is found the next day in a little wood just off the path she would normally take. A brutal murderer - soon called the Eastrepps Evil - is on the loose.

The Eastrepps Evil is a phrase coined by vacationing newspaperman William Ferris; might he also be the Evil? Or is the murderer Robert Eldridge, who with cold calculation carried on a six-months' affair with Margaret Withers in order to establish the perfect alibi? Or the shiftless Dick Coldfoot, who is blackmailing Eldridge? Or Alistair Rockingham, who has an eye for the ladies and certain compulsions that go beyond merely tipping his hat? Or is it someone else in the formerly sleepy seaside village of Eastrepps?
