Sách nói: Tom Ossington's Ghost

Madge and Ella have lived at Clover Cottage for six weeks when a series of strange events begin to occur. A gentleman who arrives asking for a piano lesson from Madge, suddenly bolts out the back door and over the hedge when he sees a rough-looking character watching him from the street in front of the cottage. This man in turn, runs away when he sees a shabbily dressed woman come around the corner. The woman, marches into the cottage, declaring that the cottage is haunted, and she is the wife of the ghost! An attempted burglary, and a cryptic note left at the scene, just add to the mystery.
