As the creator of Charlotte and Thomas Pitt, Anne Perry knows a thing or two about unlikely detective duos. Here she curates a short story collection of 19 such pairings, including her own "Reconciliation," as well as selections by Joe R. Lansdale ("Sad Onions: A Hap and Leonard Story"), Charles Todd ("Blood Money: An Inspector Rutledge Story"), Jeffery Deaver ("Security"), and Jacqueline Winspear ("The Wagatha Labsy Secret Dogtective Alliance: A Dog Noir Story"). Other contributors include William Kent Krueger, Amanda Witt, Claire Ortalda, Ace Atkins, and Shelley Costa.
