Driven - Leipfold Mysteries, #1

Meet private detective James Leipfold, computer whizzkid Maile O'Hara and good-natured cop Jack Cholmondeley in the first book of the Leipfold series. A car strikes in the middle of the night and a young actress lies dead in the road. The police force thinks it's an accident, but Maile and Leipfold aren't so sure. Putting their differences aside, and brought together by a shared love of crosswords and busting bad guys, Maile and Leipfold investigate.
But not all is as it seems, as they soon find out to their peril...
