This novella was created by Edgar Wallace, a famous British author of mystery genre. Best remembered for penning the screenplay for the classic film King Kong, he was an astoundingly popular luminary in the action-adventure genre in the early twentieth century. The Man Who Killed X" is a story packed with intrigue, treachery, assassinations, and machinations, and it highlights Wallaces unmatched skill in setting a pulse-pounding pace. Its all great fun and Wallace keeps the action moving along swiftly, as he always did. Wonderful entertainment and highly entertaining. If you havent discovered the joys of Wallaces thrillers there is a good place to start. Highly recommended.
