You’ve Attended the Tale of Sweeney Todd. Now Hear Mrs. Lovett’s Story.

THE BUTCHER’S DAUGHTER: The Hitherto Untold Story of Mrs. Lovett, by David Demchuk and Corinne Leigh Clark

For half a century — much longer, if you go back to the original 1840s penny dreadfuls — people have thrilled to the story of Sweeney Todd, the murderous London barber who cut short the lives of priests, fops, sailors and one especially loathsome judge before he met his own gruesome end. Sweeney’s tragic losses and appetite for vengeance have been well documented, most notably by the musical genius of Stephen Sondheim. But what of his partner in crime, Mrs. Lovett, who popped his poor victims into her pies? Does her tale not need attending, too?

David Demchuk and Corinne Leigh Clark’s epistolary novel “The Butcher’s Daughter: The Hitherto Untold Story of Mrs. Lovett” gives the woman beside the man her own turn in the spotlight. Part Victorian historical fiction, part grisly horror, the book follows a mysterious woman, Margaret C. Evans, a.k.a. Margery, as she recounts her life story to a never-seen (and, we learn at the opening of the book, missing) journalist, who is investigating the disappearance of Mrs. Lovett 50 years before. Though she does not disclose her true identity outright until fairly deep in the novel, it is clear within the first few pages that Margery is Mrs. Lovett, who — in a departure from the source material, where she is killed by Sweeney — is very much alive and confined to a nunnery.

Margery’s harrowing tale reframes Mrs. Lovett not as a villain but as a maligned girl fighting to survive. She’s a seductively evocative narrator, making it easy to forget that her every word should be taken with a hefty pinch of salt.

It will surprise nobody familiar with the musical that this is a gory book. The violence starts early, at Margery’s father’s butcher shop, where she is awakened each morning by the sounds and smells of sheep being slaughtered, and where it is a shame bordering on sin to let anything go to waste.
