Betrayers: A Nameless Detective Novel

Sullivan, a veteran of more than a dozen Nameless titles, keeps it straight for listeners. He also plays to the humanist side of the characters as they pursue the perps of relatively low-violence crimes.

Sullivan delivers a polished, unobtrusive performance and transitions smoothly among the characters. Recommended.

Pronzini has taken to giving readers three cases per novel, one involving each of the agency's three principals. And, as always, each case reveals a little more of each character, which at this stage of the series-more than 30 novels plus short stories-is the greatest pleasure of all.

Solid as ever, with funny, ballsy Tamara continuing to buff her role as designated scene-stealer.

For each of the detectives at the agency, a betrayal becomes not only the driving force behind an investigation, but the source of the kind of resolve that cannot be derailed by threats. For Nameless, trying to find out who is gaslighting an old woman only exposes the ugly side of family.
