Chapter 19 Summary

The Heart of Gold has landed on Magrathea, and the travelers are preparing to disembark the ship, taking Marvin (the paranoid android) with them, when Trillian realizes the white mice she has brought from Earth have escaped. Zaphod is not concerned, although Trillian (who had Earth degrees in Math and Astrophysics) was much attached to her lab mice. Nevertheless, they exit the starship, not realizing that the hatchway opens and closes again behind them for no apparent reason.
