"I start with zero. Nobody dies today."

The strange note was just the beginning. Soon Howard County, Maryland Detective Lieutenant Rick Peller is in pursuit of a cunning killer basing murders on the Fibonacci series, a mathematical sequence in which each number is the sum of the preceding two. And all Peller knows for sure is that the series never ends.

As the murders pile up, Peller, his protégés Detective Sergeants Corina Montufar and Eric Dumas, and consulting mathematician Tomio Kaneko race against time to identify and capture the killer. Nor is murder their only problem. Simultaneously, a golf-club wielding mugger is terrorizing their community. Both crime sprees are wrapped in impenetrable mystery. Are mugger and murderer one and the same? Why does the murderer seem to know Peller? Why is the Pentagon eager to keep a lid on the investigation? Can the detectives find the killer before he commits his final, terrible crime?

A thrilling, fast-paced crime drama, The Fibonacci Murders is the first of Dale E. Lehman's Howard County Mysteries.
