No one has a nasty word to say about Gerald Foster. Polite and industrious, he married his employer's daughter, Vera Murdoch, shortly after the old man's death. Nine years later Vera has become a rather faded flower and a hypochondriac, yet the business has prospered under Gerald's loving care. Then, however, Vera is found dead of a drug overdose while alone in the house with her temporary companion-nurse Edith Jordan; and though suicide is the inquest verdict, Chief Inspector Kelsey is convinced that Vera was murdered. (He catches a conspiratorial glance between Edith and Gerald.) Both murderer and method are, in fact, promptly revealed--but, thanks to Page's assured style, the suspense never flags as Kelsey and Sergeant Lambert secretly build their case, then see it fall apart, to be finally resurrected by a chance encounter. This coincidence is, admittedly, one of rather too many here--but Page (Add a Pinch of Cyanide, 1973) deftly spins it all in, and this is modest but distinctly high-class entertainment.
