1878–1959
Best remembered for a brisk juvenile mystery from the late 1930s, this little-known writer brought cameras, fog, and city crime together in a story built for young adventure readers. Surviving public records about the author are scarce, which gives the work an extra air of old-book curiosity.

by David O'Hara
David O'Hara (1878–1959) appears to have been a relatively obscure author whose best-confirmed surviving book is Jimmie Drury: Candid Camera Detective, published in 1938. The novel follows a young photographer-detective and has remained available through later reprints and Project Gutenberg, which is why O'Hara's name still turns up for modern readers.
Reliable biographical information beyond those basic dates is limited in the sources I could confirm. Rather than repeat uncertain details, it's safer to say that O'Hara is remembered today mainly through that one juvenile mystery, a fast-moving period piece that reflects the era's enthusiasm for amateur sleuthing and gadget-like ingenuity.
For readers browsing older adventure fiction, O'Hara's appeal is the sense of discovery: not a famous literary figure, but a writer attached to a vivid, forgotten corner of 1930s popular storytelling.
