Daredevil is the title of a mystery novel by Leslie Charteris which was first published by Ward Lock in 1929 (followed by an American edition that same year by The Crime Club).
This was Charteris' fourth full-length novel, and is one of the few full-length books in his canon that does not feature the character of Simon Templar, alias "The Saint".
The character featured many elements that would later be incorporated into The Saint (including the car he drove, a Hirondel, of the type later used by Simon Templar in the early Saint novels and stories).
The most notable element of the book is that it featured the first appearance of Scotland Yard Inspector Claud Eustace Teal, the gum-chewing detective who later became a recurring character in the Simon Templar novels, novellas, and short stories starting in 1929 (Templar had been introduced in the 1928 novel, Meet - The Tiger!
Charteris would go on to write one further novel in 1929, The Bandit, before focusing almost exclusively on writing Simon Templar adventures (with a few exceptions) for the remainder of his literary career.
