Pseudonym of the British author born Richard Bernard Heldmann. He is best known for his supernatural thriller The Beetle: A Mystery, which was published in the same year as Bram Stoker's Dracula and was initially even more popular.
Heldman was educated at Eton and Oxford University. He began to publish short stories, mostly adventure tales, as "Bernard Heldmann," before adopting the name "Richard Marsh" in 1893. Several of the prolific Marsh's novels were published posthumously.
