No case is too strange or too baffling for the policeman George Felse and his son, Dominic. Over 13 instalments and two decades, the Felse Investigations will take them from their home on the Welsh Borders to the southernmost tip of India. On the eve of her 41st birthday, Bunty Felse is overcome with depression; the weather is dreary, her only child Dominic fails to call with birthday greetings, and her husband, George, arrives home only to announce that he has to leave for London immediately to attend to urgent police business. After almost 20 years as a detective's wife, Bunty doesn't protest or complain; she sends George off with a swiftly packed case. To shake off her black mood, Bunty goes out for a solitary evening walk. She stops at the local pub for a drink and accepts a lift home from a sad young man whose troubles draw her out of her own and makes her feel compelled to help him. But as soon as the car door closes, the driver reveals a dark secret that could lead them both to an early grave. Will she manage to escape the mysterious fugitive before it's too late?
