Mike Mansfield’s cases are never easy. They’re dangerous and unpredictable, but there are patterns. Patterns in how criminals act and how they think. But this time, something is off. After a recent rescue, the emerging details seem very odd to Mansfield. Of his three culprits, one has no clue who he was working for, the second has no desire to be released from police custody, and the third has vanished altogether. Moreover, the level of sophistication involved in their operation is beyond anything he's seen before, and hints at something much more ominous.

Unfortunately, what Mansfield and his invisibles don't know yet … is that they have severely underestimated what they’re up against.
