FATALLY INFERIOR

Three detectives investigate the disappearance of Charles Darwin’s daughter-in-law in Squire’s historical mystery.

Archibald Line, London’s former chief of detectives, is already investigating the sender of a mysterious, threatening letter sent to scientist Charles Darwin’s home when he is called back to assist with a more pressing matter: the disappearance of Darwin’s daughter-in-law Henrietta. Line soon learns that Henrietta has been missing for four days and that the current chief of detectives, Jeremiah Fickett, is already on the case. Line also sends a personal note to Dunston Burnett, a retired bookkeeper who initially seems positioned as a Watson-like figure to Line’s Holmes, though Burnett soon launches his own investigation. Interspersed between these three strands of investigation is the initially curious story of Lucy Kinsley, a woman fallen on hard times who has just had her baby taken from her when Lucy is officially pronounced dead (though she’s still alive). Traversing these eventually converging narrative paths, Squire presents different views of Victorian London. The Lucy sections are particularly grimy: “The nurse on duty was asleep in a chair, totally oblivious to the ugly sounds issuing from the forty or so beds crammed into the ward. If the moaning, sobbing, and occasional scream were not enough to wake her, then quiet-as-a-mouse Lucy was not likely to disturb her.” The author also skillfully creates tension by cross-cutting between the investigative threads. By the time another letter appears at the Darwins’ doorstep, and a body that might be Henrietta’s is discovered along the Thames, readers will be racing through the chapters. Lucy’s section slows the momentum in the first third of the novel, but her role in the mystery becomes clearer as the story unfolds. Alongside the sleuthing runs a discussion of the transformational impact of Darwin’s work and the fiery response it received from religious leaders and believers.

A layered and fast-paced mystery that also takes time to explore the importance of Darwin’s work.
