Few would argue with the contention that no better writer has ever tried her hand at writing detective fiction than Dorothy L Sayers. I happen to like good writing, and I don't mind if it features more strongly than the puzzle component in a mystery novel.
"Strong Poison" abounds in wit, charm, characterization, and literary excellence. This is the one that begins with two whole chapters of a judge's summing up. On trial is Harriet Vane, accused of killing her lover by administering arsenic. All believe she is guilty except one jury member, Miss Murchison, who prevents the jury from bringing in a "guilty" verdict, and someone attending the trial, Lord Peter Wimsey, who determines to prove Harriet's innocence and make her his wife.
Dorothy L Sayers then makes little pretence at hiding the identity of the killer. Instead she unfolds a fascinating investigation into how the crime was committed and how Lord Peter and one or two helpers collected the evidence to convict.
Neither as long nor as long-winded as some of Miss Sayers' later detective fiction, this one offers rich and pure pleasure all the way. The additional luxury of hearing it read by Ian Carmichael in audio book form is well worth investigating.
