Obsessions is the 222nd episode of The Bill.
W.D.C. Martella is called to a solicitor's house where one of his clients has come to see if he will keep his promise to marry her. The client has made threats to kill the solicitor's wife and later attempts to run her down in a car park. W.P.C. Ackland and P.C. Stamp are called to deal with a barking dog in a house. Just as Stamp breaks the glass in the front door, the neighbour tells them that she has a key. Ch. Insp. Conway thinks there have been backhanders from contractors to the clerk of works. Ch. Supt. Brownlow tries to get Conway to take some leave.
