Doc Martin: Boho with a Shotgun

Sleepless nights are taking their toll on Martin and Louisa and tempers are starting to fray. Aunt Ruth has problems of her own - a thief has stolen the hub caps from her car. The thief is identified as Michael Dunwich, who lives with his mother Shirley on a neighbouring farm. Later, Shirley tells Martin about her crippling stomach pains and reveals that she thinks her son is trying to poison her. New receptionist Morwenna Newcross arrives late on her first day, but when her grandfather William gives her some pills to make sure she wakes up on time, Martin thinks that she is high on drugs and fires her.
