"Strong Poison" is the sixth book in Dorothy L. Sayers's "Lord Peter Wimsey" series of mysteries featuring the quick-witted and insightful "gentleman detective."

This volume begins with mystery novelist Harriet Vane on trial for poisoning her former lover, Philip Boyes. Although the evidence appears overwhelming, Lord Peter Wimsey refuses to believe she is guilty and launches a determined investigation to clear her name before the execution. His inquiry exposes Boyes's complicated relationships, shifting loyalties, and the bitterness surrounding his controversial views on marriage and free love.

Alongside the murder plot, Sayers explores prejudice, gender, intellectual independence, and the limits placed on women who challenge social conventions. The novel balances courtroom suspense with wit, moral seriousness, and penetrating social observation.

"Strong Poison" is presented her in its original and unabridged format.
