A bar turns into a gory battlefield during happy hour with patrons killing each other under an airborne hallucinogenic drug. The bar's owner is Roarke, but his wife, Lieutenant Eve Dallas, doubts the attack was directed at him. Then a popular restaurant is hit during lunch hour with patrons exhibiting the same symptoms and Eve knows she's dealing with a madman.
I liked this one. It wasn't perfect, especially in the pacing department (although it did pick up the tempo for its second wind), but it delivered.
I dug the procedural aspects of the story, the little tidbits of (fictional) history, and the whole mass-murder under the influence of an airborne hallucinogen, although I did find the motive beyond lame, idiotic, and unworthy of the "historical figure" the killings emulated.
The cast was superb, as always, with their relationships evolving in front of out eyes book to book, especially Eve/Peabody and Eve/Mira (I loved how Eve's mother figure helped her deal with her dreams).
It was a little different, and different is (always) good.
