Certain Prey (Lucas Davenport Series #10) Book

The 10th Lucas Davenport novel is one of his most popular because, I believe, it is a study of opposites and contrasts. Davenport crosses more than a few lines in pursuit of a murderer and the professional killer she's hired. Meanwhile the assassin is an extremely sympathetic character. When a complication arises that may trace back to the hired killer, the instigator arranges a meeting and is surprised that the killer is a woman. As each complication is removed, another grows; and the developing friendship between the women is yet another contrast. The thriller aspect becomes almost secondary as the book races to its conclusion.
