New York: The Century Co., 1918. Hardcover first edition - Seaman's first book for younger readers ('the very little boys and girls between the ages of six and ten years') and perhaps the best of these books. A charming story of two lonely children - Melissa who lives in the top floor of a very small house - and Victor, who moves into the grand house behind hers - and how they communicate by messages held up to the window. Illustrated by C. M. Relyea with a frontispiece and 2 glossy plates. 121 pp. Bound in tan cloth with black lettering on the spine and front cover, and a black, pink and green illustration on the front cover (a simplified version of the frontispiece).
