Book One of the Cal Mercer Series
Pattern of Life
Three signals that should not exist, a death the file has already closed, and an analyst who has never been able to leave a question alone.
The Book
A dead system that will not stop talking.
Cal Mercer reads signals for the NSA at Fort Meade. He is an analyst, not a field man, and his gift is the shape inside the noise that everyone else has filed and forgotten.
One February morning he finds three emission signatures attributed to platforms decommissioned years ago, all routed through a single collection node, all too clean for the hardware they are hung on. Dead systems do not transmit. Following the anomaly means reopening a death the agency long ago ruled a suicide, and learning that the proper channels for reporting what he found run straight through the people he would have to report.
Cal Mercer
The man at the desk.
Caleb Mercer came up through Army signals, the way you learn a trade where being wrong has consequences the same afternoon. He bet his twenties on Russian in 2008, when the language was an empty seat nobody wanted, because he had watched the thing he studied come true and decided the seat would matter. He enlisted rather than took a commission, on the theory that a contract guarantees the work and a commission guarantees meetings. He trained as a cryptologic linguist and spent his years on the objective with a rifle and a collection kit while other men kicked the doors, and he was never confused about which of those two jobs was his.
In the autumn of 2015, in Syria, he heard a pattern nobody had a precedent for and wrote it down plainly. A senior officer buried the assessment because it had never happened before, and a man Mercer had listened to for the better part of a year went where the assessment said not to go. He separated a few months later. The NSA hired a man it already knew: the language, the years, the deployed tour.
He is not a field man and does not pretend to be. What he is good at is the shape inside the noise, and the one habit he has never been able to break, which is refusing to leave a question alone once he has seen it.
He listened to what people meant, which is a different thing from having a good ear, and it is the whole of his trade.
