David O'Hara

Very little biographical information about this author is readily confirmed online, but library and ebook records identify David O'Hara as an author born in 1878 and deceased in 1959.

The work most clearly connected with him is Jimmy Drury: Candid Camera Detective, a juvenile mystery novel published in 1938 and later preserved by Project Gutenberg. The story follows a young amateur sleuth who uses his camera as part of his crime-solving, giving the book a fun hook that blends photography, suspense, and classic adventure.

Because reliable source material on his life is scarce, his reputation now seems to rest mainly on that surviving novel and its place in early 20th-century popular fiction for younger readers.
