Ernest William Hornung 
Dead Men Tell No Tales [PDF ebook] 

An English author who gained fame with a series of novels about a raffish but lovable thief named Arthur J. Raffles, Ernest William Hornung also tried his hand at mystery and detective fiction, perhaps inspired by his brother-in-law, Arthur Conan Doyle, the creator of master detective Sherlock Holmes. In Dead Men Tell No Tales, Hornung spins a yarn that starts out with a love affair that blossoms on a boat journey, but soon turns deadly. A must-read for lovers of classic detective fiction.
