'Clostin is not a pleasant man to have dealings with. He is agreeable enough to meet for he has charm and an easy manner. But he is in all things an opportunist, a schemer. He married for money, calculatingly, and for all his casual airs there is something calculating about everything he does. From the very beginning of tonight's play Clostin is planning something. For much of the time he is improvising, feeling his way, trying cleverly to find out what his wife Anne has in mind, where Peebles fits in, what Hurst has learnt from the others. And if this shrouds the play in mystery that is as it should be, for it is a play of detection, a subtle account of a battle of wits.'
