Blurb

The Assassination Bureau, Ltd is a thriller novel, begun by Jack London and finished after his death by Robert L. Fish. It was published in 1963. The plot follows Ivan Dragomiloff, who, in a twist of fate, finds himself pitted against the secret assassination agency he founded.
The novel was based on a story idea London purchased from author Sinclair Lewis in early 1910. London wrote 20,000 words on the novel before he gave it up later that same year, saying he could not find a logical way to conclude it. He died in 1916, leaving the book unfinished.
The novel is about a secret organization, The Assassination Bureau, Ltd., that will assassinate evildoers, for example, corrupt police commissioners, legislators, politicians, etc.; but will not act unless convinced that the target truly is worthy of assassination.
In 1963, mystery writer Fish completed the novel based on the unfinished manuscript with additional notes by London and an ending outline done by London's wife Charmian shortly before her death in 1955.
