By the author of a number of mysteries set in picturesque surroundings (Mystery by Moonlight 1963; Mystery at Dead End Farm, 1961) this one has been placed in an old house in the shadow of the Longfellow memorial. Miss Goddard, an elderly devotee of the poet, takes on Phil Holt's mother to assist her in a book she is writing. When Phil is left alone with Miss Goddard after his mother has been called away to look after a sick relative, he becomes suspicious of a visitor who seems to be taking a peculiar interest in the house. Assisted by some of his friends and a dog, Phil catches the man in the act of trying to steal Miss Goddard's will. A mild rather dull suspense story spiced with frequent quotations from ""Hiawatha,"" ""Evangeline,"" and other poems by Longfellow.
