The romance of crime

"The TARDIS brings the fourth Doctor, Romana and K-9 to the Rock of Judgment: a court, prison and place of execution built into a rocket-powered asteroid. There they become embroiled in an investigation by the system's finest lawmen. What connects the macabre gallery of artist Menlove Stokes with the slaughter of a survey team on a distant planet? Why is Margo, chief of security, behaving so strangely? And which old enemies of the Doctor are aboard the unmarked spaceship making its way towards the Rock? This adventure takes place between the television stories The Creature from the Pit and Nightmare of Eden."--Page 4 of cover.
