Christie Malry's Own Double-Entry (1973) is the penultimate novel by the late British avant-garde novelist B. S. Johnson.

It is the metafictional account of a disaffected young man, Christie Malry, who applies the principles of double-entry bookkeeping to his own life, "crediting" himself against society in an increasingly violent manner for perceived "debits".

Every aggravation Malry suffers from society—such as being forced to walk along a particular stretch of pavement due to a building's placement—is revenged by a recompense—in this case, "[scratching] an unsightly line about a yard long into the blackened portland stone facing of the office block" (23–4).

Having established this system, and growing progressively angrier at society, Malry graduates from minor acts of personal revenge (mostly vandalism) to large-scale terrorism: bombing hoaxes, an actual bombing, and poisoning West London's drinking water.

Christie compares himself to "Guy Fawkes, with the difference that he was caught" and strictly follows a code of twelve principles.

It was directed by Paul Tickell, written by Simon Bent and starred Nick Moran as Christie.
