The Dark Tide

Gross, who’s partnered with James Patterson on a number of bestsellers (Lifeguard , etc.), mixes murder, suspense, sex and romance as capably as his mentor in his assured second solo thriller (after The Blue Zone ). Charles Friedman, a New York hedge fund trader, perishes in a bombing at Grand Central Station that destroys the railroad car in which he was riding one morning from his home in Greenwich, Conn. Ty Hauck, head of the Greenwich police’s violent crime unit, enters the picture when a hit-and-run victim turns out to have a vague connection to Friedman. Soon, Friedman’s widow and her kids are threatened by men searching for vast sums of money her late husband never earned. The stakes rise as Hauck’s involvement shifts from professional to personal. While the reader will occasionally see the next drop, tunnel or curve looming far ahead, the roller-coaster thrills are still there in abundance. (Mar.)
