State of Mind

An elderly man reports an unusual break-in, during which the uninvited visitor left a mysterious statue on the kitchen table. It soon emerges that it is just the first in a series of unexplained events, as a police phone box arrives and then disappears from his garden, cement is delivered to his house for no apparent reason and a fire is started in his garage. Acting Sergeant Nokes advises Steve to dismiss it as it is not technically a police matter, but the officer's curiosity causes him investigate further. Meanwhile, Vernon is called up for jury service, but soon finds it's not as much fun as he hoped, whilst David is left to hold the fort back in Aidensfield in his absence. Elsewhere, Gina goes back to Liverpool as her dilemma about her imminent wedding continues.
