Jackie gets a visit from her old friend Caroline. She is surprised to learn that Caroline has a baby. Caroline needs a day off from motherhood and leaves the baby with Jackie and Mike while she goes to York to see some friends. Mike leaves the baby in a pram outside the police house, but when Jackie comes home from an errand the baby is gone. Jackie is not the only one who has a visitor. Lady Patricia visits her brother at Ashfordly Hall together with an old family friend Lord Hal Tadcaster. Well "together" may not be the proper word, because she would rather see him leave than stay. And with good reason since the CID suspects Tadcaster of being a drug dealer and asks the police in Ashfordly to keep an eye on him. The post office in Whitby goes on strike. Vernon Scripps gets the idea to start a courier service. And for once he does the dirty work himself.
