New York: Century, (1918.). Hardcover - One of Seaman's earlier mysteries, and one of her more appealing stories in many ways: it is the only one of her books to be set in Connecticut, in a thinly disguised version of her mother's hometown of Stratford, and is notable for its careful attention to pre-Revolutionary architecture. It is also the first of her mysteries to bring in the theme of the survival of Louis, Dauphin of France. Written in the first person, in lively journal entries by a young Helen Roberta - called Bobs - this is set against the backdrop of the first World War raging in Europe, although the United States is not yet involved. This book was dedicated by Seaman to 'the real Helen Roberta', her daughter, called Bobbie. Illustrated by C. M. Relyea with a frontispiece and 3 glossy plates. 275 pp.

New York: Century, 1920. Hardcover - One of Seaman's earlier mysteries, and one of her more appealing stories in many ways: it is the only one of her books to be set in Connecticut, in a thinly disguised version of her mother's hometown of Stratford, and is notable for its careful attention to pre-Revolutionary architecture.

New York: The Century Company, 1921 (c 1919). Hardcover - Mystery set in a rural area of New Jersey - on the 'Manituck River'- where Seaman had lived with relatives during part of her childhood. The two girls - new friends - who get involved in the mystery surrounding the old house - are contrasted very nicely in the opening scene, when Doris, the rich visitor staying at 'The Bluffs', beaches her canoe near where Sally, who helps her parents in their boat rental business, is sitting. Sally is barefoot, wriggling her brown toes in the warm sand, while Doris steps out of the canoe in 'fine white silk stockings and dainty patent leather pumps.' The setting is so accurate that a local newspaper reporter was able to trace the route that the two girls in The Slipper Point Mystery took, matching them to the actual landmarks and buildings in the area, and current local legend was that an old house sitting on a bluff high above the river had been a stop in the Underground Railroad. Illustrated with a frontispiece and 3 glossy plates by C. M. Relyea. 207 pp.

Garden City, New York: Doubleday, Doran & Co., Inc., 1937. dj. Hardcover - Novel for older girls set on the coast of New Jersey and involving an unsolved mystery from Revolutionary days. Even Seaman's books which had many printings have become very hard to find in recent years, and this title - issued in the midst of the Depression - had, as far as is known, only a first printing of only 5,000 copies (many of which went to libraries) and 2 presumably smaller later printings in 1937 and 1940, making it one of her most uncommon novels. Since it is also one of her best-realized and most satisfying books with a great ending, the fact that it is so hard to find is doubly disappointing. Illustrated by Manning De V. Lee with a 3 color frontispiece, green and white illustrated endpapers, and a portion of a 1765 map. 273 pp.

New York: The Century Co., (1926). dj. Hardcover first edition - Novel set on the remote New Jersey coast. Despite the fact that this had several printings, it remains one of Seaman's more difficult to find titles in any edition. It is also an interesting and popular story which involves 2 shipwrecks - one long ago, and one 18 years before the time of the story - and a lost treasure. Illustrated by C. M. Relyea with a frontispiece and 3 glossy plates (as a side comment, a couple of the plates show our young heroine on the beach in dainty high heeled pumps; the more realistic story has the girls changing into their 'tie-ups' before venturing off.) Bound in tan cloth with black lettering and illustration with a green background on front cover and spine. 306 pp.

New York: The Century Co., (c. 1915). Hardcover - The first of Seaman's mysteries for girls and still one of her most popular and sought-after books. As most of her best books do, this involves solving a mystery buried in the past - in this case, during the Civil War - to solve a current mystery - what is the story behind this mysterious old house? In a nod to enduring popular culture, the two friends are reading the Sherlock Holmes book "Sign of the Four" and wish they had his mystery solving abilities. Although at least 14 printings are known withThe Century Company imprint, and it was kept in print after Century merged with D. Appleton in 1933,this title remains rather hard to find. Illustrated with a frontispiece and 7 inserted glossy plates by C. Clyde Squires. 217 pp.

New York: D. Appleton-Century, 1933. dj. Hardcover - Novel originally published in 1926, and set on the remote New Jersey coast.

Relyea with a frontispiece and 3 glossy plates (as a side comment, a couple of the plates show our young heroine on the beach in dainty high heeled pumps; the more realistic story has the girls changing into their 'tie-ups' before venturing off.)
