Georgette Heyer’s “Sprig Muslin” is a charming Regency romance that takes place in 1813. The narrative centers on Sir Gareth Ludlow, a popular bachelor who chooses to pop the question to Lady Hester Theale following the passing of his true love. But when he meets the sultry and creative Amanda Smith, fate steps in. A lively competition of ludicrous lies and surprising turns results.
