Episode 26, "The Talking Head," was also the last, and the series went out on a high note. A clean shaven Hugh Griffith pops up as Dr. Ivy, ecstatic over the recent purchase of a stamp from more than 700 BC; he also tells his friend Colonel March of a patient, Harold Hartley (Hugh Williams), who has survived a murder attempt by a 12 year old boy, Andrew Barton (Peter Asher). Hartley is a close family friend who has always treated Andrew like his own son, and is now engaged to the boy's mother Phyllis (Helen Christie), since the untimely death of her scientist husband John in a plane crash. A frantic call from Phyllis reveals that Hartley has met with another 'accident,' falling down the stairs, so Colonel March journeys to the Barton home, where the housekeeper, Mrs. Wrigley (Mary Clare), eyes him with suspicion. When questioned, Andrew reveals that he tried to kill Hartley because his father asked him to, and, incredibly, the bust of John Barton actually does speak to the lad, preparing him to use poison for the next murder attempt. It's up to Inspector Ames (Ewan Roberts) to ascertain whether Barton is really dead, or else Colonel March may have to arrest a ghost! One of the best scripts of the entire series, a shame since this was the finale (lucky this show has survived, like THE VEIL, from 1958). Billed in the opening credits with Karloff and Roberts, Hugh Williams had previously worked with Karloff's former comrade in terror, Bela Lugosi, playing a Scotland Yard man in 1939's "The Dark Eyes of London." Peter Asher did fewer than a dozen parts as a child actor, while his younger sister Jane continued her acting career well into the 70s (as a child, she was in Hammer's 1955 "The Quatermass Xperiment," while later appearing with Vincent Price in 1964's "The Masque of the Red Death"). By 1964, Peter Asher had turned his attention to pop music, as half of the harmony duo Peter and Gordon (Gordon Waller), whose earliest hits were supplied by Jane's then-boyfriend, Paul McCartney, who lived at the Asher home in London for a time. By decade's end, Asher had turned to producing artists for The Beatles' Apple label in London before relocating to the US (James Taylor and Linda Ronstadt being the most successful).
