HARDCASTLE'S SECRET AGENT

Ison, who died last December, rounds off the period procedural series starring Divisional DI Ernest Hardcastle by presenting his son with a brace of murders in the opening months of World War II.

Whoever’s been burglarizing the citizens of Kingston and Surbiton has made off with so few valuables that Deputy Assistant Commissioner Charles Marriott, Hardcastle’s former sergeant, wonders if the intruder has been looking for something else. He plucks his old boss’s son, DI Walter Hardcastle, from the Flying Squad, installs him as the new Divisional DI of Wandsworth Division, and presses him to look for a pattern beneath the break-ins. The stakes are abruptly raised when Frank and Helen Roper catch the burglar at work in their home and are shot dead for their trouble. But the patient, exhaustive inquiries launched by Hardcastle and his unit go nowhere—unlike Hitler’s forces, who march into Poland, provoking England’s belated declaration of war, and begin to menace England in a series of bombing attacks. The discovery of presumed Abwehr officer Konrad Fischer, who’s pulled from the Thames still tangled in a parachute, seems promising but isn’t. Months pass before cinema usherette/working girl Joyce Butler is bashed to death and one of her mates is strangled. The sprawling investigation continues to thresh through a cast of dozens, not one of whom comes to life. Nor (spoiler alert) do the murders turn out to be connected to one another. Don’t you hate it when that happens?

A decidedly muted farewell to a long-running franchise.
