THE SINGLE TWIN

A pair of misfit private detectives ply their trade in present-day Chicago in this soft-boiled mystery.

Little, the author of Family Ghosts (2019), introduces two eccentrics with impressive detective skills who are opposites in appearance: Aberforth “Abe” Willard Allard, the divorced father of a 14-year-old daughter, is a lanky, sad-eyed legal genius, and C.S. “Duff” Duffy, the son of a C.S. Lewis fan, is short and stocky, like a former football player—although he’s never gotten close to a gridiron. Duff discovered three murdered bodies years ago, when he was a teenager, and has long suffered from serious obsessive-compulsive disorder, which derailed his promising academic career. Abe and Duff’s normal grind includes lots of legal work and occasional consults with police in which they wield their “weird-ass Sherlock Holmes power,” as one police detective puts it. The pair’s skills are tested when ex–CIA agent Mindy Jefferson gives them $50,000 as a retainer and challenges them to find her when she inevitably goes missing. Her mother, now deceased, had revealed that Mindy had a twin brother, adopted by another family at birth. But while trying to track him down, Mindy began to realize that she was being followed. When Mindy does, in fact, disappear, Abe and Duff must unravel the mystery. Over the course of this amusing novel, Little makes sure that the detectives’ quest and its resolution always provide readers with a fun page-turner. The two heroes both have intriguing backstories, and they both struggle, in different ways, with the niceties of navigating relationships with others. Especially poignant are Little’s accounts of Abe’s efforts to properly parent his growing daughter. These scenes, and the author’s generous application of sly humor throughout the story, effectively make Abe and Duff fully realized characters rather than merely nerdy caricatures.

A solid, well-constructed missing person case that features an appealing pair of quirky sleuths.
