Clarissa Mabel Blank (August 5, 1915 – August 15, 1965) was an American author. She wrote the Beverly Gray mystery series and four other novels.

Blank was born on August 5, 1915, in Allentown, Pennsylvania, to Bessie and Edgar H. Blank.^[1][2] Her father worked as a loom fixer at a local silk mill, and later at a clothing plant in the Germantown section of Philadelphia;^[1] in three consecutive U.S. census reports in 1920, 1930, and 1940, his occupation is listed as a knitter.^[3][4][5]

Blank attended Herbst Elementary School at 5th and Chew streets in Allentown until she was about ten. Her family then moved to the Olney section of Philadelphia.^[1] In contrast to her parents, who only completed nine years of schooling,^[5] Blank graduated from Olney High School with honors and published the first four what were ultimately 24 books in her Beverly Gray series by age 18.^[1] She then attended Peirce School of Business Administration, now Peirce College, in Philadelphia.

Blank began her career in Philadelphia as a typist for the Keystone Pipeline Company, a subsidiary of the Atlantic Refining Company.^[1][6][7] In 1940, she became a secretary there, and, still living with her parents, earned about $1,500 a year.^[5] She joined the American Women's Voluntary Services during World War II, where she drove U.S. Army officers when they came to town.^[1]

In addition to the Beverly Gray series, Blank authored four other novels. The first three, comprising the Adventure Girls Series, were published in 1936 by A. L. Burt, which published the Beverly Gray series. They were later republished by Saalfield Publishing. In 1940, Gramercy Books, since acquired by Random House, published Blank's only adult novel, Lover Come Back.

At least two manuscripts written by Blank went unpublished. In December 1941, she sent an unsolicited manuscript, Linda Ross at Hamilton, to Grosset & Dunlap. It was rejected for publication four months later, for "there seems to be a strong prejudice against starting a new mystery series with a school background."^[8] Blank also wrote an unpublished Beverly Gray novel to follow the final volume, Beverly Gray's Surprise.^[8] This work was never printed, as the series was cancelled in 1955. It is possible that a fourth Adventure Girls book was also written, to be titled The Adventure Girls on Vacation. This book was advertised at the end of the third and final book in the series; it is unclear whether Blank actually wrote it, or merely intended it, before the series was cancelled.

A trilogy by default, The Adventure Girls series was published by A. L. Burt in 1936 and never continued. All works were copyrighted on April 27, 1936, the same day as Beverly Gray on a World Cruise.^[9] Although a fourth work was advertised at the end of the third, it was never published; where the Beverly Gray series survived and prospered following the publication of its four part breeder set,^[10] The Adventure Girls series was unable to catch on. Purchased by Saalfield Publishing in 1937, the series was entirely shelved until being reissued in the fall of 1942.^[8] None of the books had their copyright renewed and are now in the public domain.

Blank's short-lived foray into adult literature, Lover Come Back, was published in 1940 by Gramercy, now a division of Random House. It does not appear to have ever been reprinted in novel form. Notifications in The Pittsburgh Press suggest that it was printed in a complete novel section by the Pittsburgh daily newspaper on April 13, 1941.^[11][12] As a result of this limited print run, Lover Come Back is Blank's scarcest published novel.

Lover Come Back echoes the Beverly Gray series in both plot and writing style. Just as Beverly Gray is a successful screenwriter, playwright, novelist, and reporter for the Herald Tribune, Beverly Norcot shares the same vocations and success, and reports for The Times, almost certainly a reference to The New York Times. Lover Come Back features a plot driven by events and coincidence. "In its series of mini-climaxes strung together, the book is a soap opera." The book's "major ingredients" consist of:

"3 auto accidents (2 human, 1 canine)
2 shootings
1 emergency appendectomy
3 witnessing[s] by jealous suitor of girlfriend embracing another man
3 reversals of fortune (1 downward, 2 upward)
2 sudden disappearances of boyfriends out of the country
4 unexpected reunions of same with girls
numerous reversals of feeling between lovers
frequent dashing around by characters in cars, ships, and a plane
multiple rendezvous at society parties [and] swanky nightclubs"^[13]

Beverly Gray, too, leads "such a life of adventure as would tax the resources of any soap opera heroine." Across the series, Beverly is "kidnapped no less than twenty-six times, attacked by wild animals seven times, trapped in three violent storms, imperiled by three earthquakes, shot at twice (wounded once)." She also suffers "a car crash, flowing lava, a flood, a drugging, a rampaging fire, a plane crash and other assorted tribulations."^[14]

In 1941, George Elmer Moyer,^[15] who Clair knew while growing up in Allentown, moved to Philadelphia;^[1] the two married two years later, in 1943.^[16][17]

Moyer attained the rank of sergeant while serving in the U.S. Army for two years, from February 1944 to February 1946 at the end of World War II.^[18] A skilled welder,^[19] he was employed at the Budd Company after his military service, working on automobiles, tank construction, Chevrolet fenders, and plastics until his retirement.^[1] He also took night classes in mechanical engineering at Drexel University in Philadelphia.^[1][20] Blank gave birth to two sons, Robert G. and John C. Moyer, who were born in 1947 and 1953, respectively.

Blank died on August 15, 1965, in Philadelphia;^[2] her husband died on February 27, 1998.^[20]
