Mystery / Casting: 5m, 7f / Scenery: Interior
The announcement in the local paper states time and place of a murder to occur in Miss Blacklock''s Victorian house. The victim is not one of several occupants, temporary and permanent, but an unexpected and unknown visitor. What follows is a classic Christie puzzle of mixed motives, concealed identities, a second death, a determined Inspector grimly following the twists and turns, and Miss Marple on hand to provide the final solution at some risk to herself in a dramatic confrontation scene just before the final curtain. "Had the first night audience on the edge of their seats." Evening Post. "Re enter Agatha with another whodunit hit, another of her fiendishly ingenious murder mysteries." London Evening News.
