Trigger Mortis is a 2015 James Bond novel written by Anthony Horowitz, and the latest Bond novel to be commissioned by the estate of Bond's creator Ian Fleming. The book, which will be published on 8 September 2015, is set in 1957 against the backdrop of the Space Race, and begins two weeks after the events of "Goldfinger" (1959). It will also contain previously unpublished material written by Fleming for an unfilmed television series, "Murder on Wheels", which Horowitz has used to write the opening chapter. The novel, the first in the literary series to be set during the original timeline created by Fleming, sees the return of Bond girl Pussy Galore, who made her debut in "Goldfinger". The book was announced on 28 May 2015 to coincide with Fleming's 107th birthday.
