is a novel by Douglas Preston and Lincoln Child first published in 2012. It is part of their informal Agent Pendergast
series, and the final novel in the Helen Trilogy story arc.
This novel provides examples of:
- Brazil Is Naziland
- Break the Haughty: Continues the trend of doing this to Pendergast from the previous novels of the Helen Trilogy, only it turns it Up to Eleven. Helen dies - for real this time - and later Pendergast learns that he is the biological father of two twin boys carried by Helen.
- Late Arrival Spoiler: Despite the fact that Helen still being alive was a major twist in the previous book, the synopsis on the inside cover completely blabs it away, pretty much assuming that everyone has already read Cold Vengeance.
- Tykebomb: Alban.
- The Unfavorite: Tristram. Before Pendergast finds him, he was previously known only as "Forty-seven," as he was considered the "bad twin" to the "perfect" Alban.
