Keef the Thief: A Boy and His Lockpick is a video game developed by Naughty Dog and published by Electronic Arts.

As the title character the player must steal as much as they can with the ultimate aim of accessing and looting the city treasury.

As well as exploring the city the player can also visit other locales including dungeons, jungles and an arena.

The contract was agreed after the developers had cold called Electronic Arts' helpline and ended up speaking to a producer.

[clarification needed][2] The Amiga and Apple IIGS versions of the game were reviewed in 1990 in Dragon #157 by Hartley, Patricia, and Kirk Lesser in "The Role of Computers" column.
