Super addition to the Amos Decker series. I haven't read the Wil Robie series but clearly I've been missing out on a good one and will be starting on it soon.
Amos seems to be losing some of his edge -- his "psychic" ability seems to be coming and going but mostly going having him rely on his very intelligent mind and skills. His memory does play into the story and readers are given just enough clues to follow along with him. But there are the usual, wonderful twists and turns to the story so the ending you think is coming doesn't quite happen that way.
Can't wait for the next entry.
