When Malcolm spots an advertisement for Mystic Mack's Grow A Ghost, he jumps at the chance to have a butler ghost to do his chores and homework, and spy on his sister--but soon things start to go wrong, and this ghost proves difficult to get rid of.

When Grandma Eunice gives Malcolm a strange bottle that she "won" during the 1939 World's Fair, it turns out to contain the ectoplasm of the performer that she tricked--so if Malcolm wants to keep his bottle he is going to have to figure out how to evict this stubborn ghost.

When the ghost of a rock star interferes with a music concert that Dandy, Malcolm, and his sister Cocoa are attending, the ghost detectors are on the job--but this time the key to victory may be a video game.

In this first volume of three stories, ten-year-old best friends Malcom and Dandy thwart a practical-joking poltergeist, rid the Miller house of a ghost, and get to the bottom of some unusual paranormal activity in their elementary school.
