author
Best known as the co-author of a late 19th-century mystery novel, this writer is a notably elusive figure. Very little biographical information survives, which gives the work an extra touch of literary mystery.

by Bert Leston Taylor, Alvin T. Thoits
Alvin T. Thoits is credited as the co-author, with Bert Leston Taylor, of Under Three Flags: A Story of Mystery, a novel published in 1896. Modern catalog and public-domain sources consistently link his name to that book, but they offer almost no personal background beyond the byline.
Because reliable biographical records are so scarce, not much can be said with confidence about his life, career, or other writings. That makes Thoits one of those authors known mainly through a single surviving work rather than a well-documented public life.
For readers, that absence of detail can be part of the appeal: Under Three Flags comes from a period when popular fiction mixed romance, suspense, and melodrama freely, and Thoits remains a shadowy presence behind it.
