The Dark Tide — Andrew Gross

On the morning Karen Friedman learns that her husband, a hedge fund manager, has been tragically killed, Detective Ty Hauck begins his investigation of another man's death in a suspicious hit-and-run in Karen's hometown. The two seemingly unrelated tragedies are about to plunge a beautiful widow and a determined investigator into a maelstrom of murder, vast sums of missing money, and international conspiracy.
