Another fast-paced murder mystery by J.S. Fletcher told in the first person. He wrote about 200 books on a wide variety of subjects, both fiction and non-fiction. He was one of the leading writers of detective fiction in the "Golden Age". It was first published in 1920, and has just the right stock of truly good characters, balanced by a couple of nasties. A young apprentice solicitor in a rural English town bordering Scotland, is riding his bike through lonely stretches of countryside very late in the evening, to run a strange errand for a mysterious lodger at his mother's house. He finds a recently murdered body at the end of his ride, and the mysteries keep piling up from there.
