Matt Roush: Does Nora Roberts really publish more frequently than James Patterson? Hard to imagine. (Unless, like Patterson, Nora farms her name out to other writers. But I digress.) But otherwise, fun idea.
And here's a few suggestions, minus elaboration, from Sherree: "Kathy Reichs (Bones series), Carol O'Connell (Kathy Mallory series), Robert Crais (Elvis Cole and Joe Pike series as well as others), John Sandford (Prey and Virgil Flowers series), J.A. Jance (J.P. Beaumont and Joanna Brady series), Harlan Coben (Myron Bolitar series)." Some good picks here, but it seems unlikely Kathy Reichs would spend time with another fictional sleuth, as she's already committed to one over on Fox.
