First in Macmillan's ""Murder Revisited Series"", this was published by Dutton, in 1929, under the pseudonym of Gordon Daviot. It is Inspector Grant's first case and is solid proof for the unreliability of circumstantial evidence. Once the identity of the dead man in the theater queue has been established, Grant build up a whole case against a logical suspect, corners his quarry -- and finds his doubts of the man's guilt are valid. The real killer is self-confessed and Grant is vindicated. No preparation for the ending weakens this -- but for one more Tey, give thanks.
