"The premise: inflexible. The first act was devoted to murky upper-middle-class perfidy, a tangled stumble-footed mess that ended with a corpse on the potting shed floor. (Dressed in suit, face down.) This was your chance to pick a horse: was it the earnest plain wife, the scheming sister, the dull-eyed handyman, the oily blackmailer, the strange 'Colonel Mustard' who said he had to fetch a candlestick from the conservatory? You’d never know who made the roscoe bark until the last scene, but one thing was certain: whoever went to Perry first was innocent."
