La Abadía del Crimen (The Abbey of Crime) is a video game written by Paco Menéndez with graphics made by Juan Delcán and published in 1987 by Opera Soft.

Paco Menéndez and Opera Soft were unable to secure the rights for the name, so the game was released as La abadía del crimen.

He also explains to Fra William that he is obligated to obey the orders of the abbot and the rules of the monastery, attend religious services and meals and stay in his cell at night while the research of the crimes is pursued.

The game was originally developed for the Amstrad CPC 6128 8-bit platform and ported to other systems: ZX Spectrum, MSX, and MS-DOS.

The music played in the game corresponds to the Minuet in G major and the sonata for flute BWV 1033 by Bach, and Crystal Palace from Gwendal.

The original PC version also featured "Ave Maria" from Schubert, in a short chorus recording that played through the speaker when the player went to the church.
