Dirk Gently, Monday, April 23

ABC2, 9.30pm: series premiere

Making a refreshing change from cops pounding bleak British beats, Douglas Adams' self-styled sleuth, Dirk Gently (Stephen Mangan, Green Wing), ponders the ''interconnectedness of everything'' when investigating the disappearance of an old lady's cat. Enlisting the companionship, if not exactly the help, of his friend MacDuff (Darren Boyd, who also appeared in Green Wing), Gently uncovers a mysterious exploding contraption, which may or may not have anything to do with MacDuff's relationship woes. Deliciously baffling while eliciting a strange kind of sense, this four-part series promises to please cult fans as well as intrigue newcomers to Adams' metaphysical world.
