I, Lucifer (O'Donnell novel)

I, Lucifer is an action-adventure novel by Peter O'Donnell first published in 1967, featuring the character of Modesty Blaise, whom O'Donnell had created for a comic strip several years earlier. It was the third novel to feature the character.

I, Lucifer introduces parapsychology, a theme that would recur in later books in the Modesty Blaise series; Willie Garvin has the ability to predict danger by his ears prickling, and a villain has the ability to predict future events. The novel also introduces the secondary character Steven Collier, a parapsychologist, who makes numerous future appearances in both the comic strip and the novels. The titular character, depicted as an insane young man who believes himself to be the overlord of the underworld, demonstrates the ability to predict natural deaths.
