Beloved series character Sid Halley, a champion jockey, makes a welcome return in the latest fast-paced crime novel from bestseller Francis (Come to Grief). When a crippling injury forces Halley into retirement, he begins a second career as a PI. Thanks to his doggedness and integrity, he attracts many clients, including a mysterious government figure who asks him to assess the unintended consequences of Britain's legalization of Internet gambling, and others who wish him to unravel the nest of puzzles surrounding the murder of a jockey, Huw Walker, suspected of throwing races. This time, the sinister forces arrayed against him have an unexpected weapon—threats of violence against Halley's new significant other. The writing and action are as crisp as ever, though longtime Francis fans may find the plot a little familiar. BOMC and Mystery Guild main selection.(Sept.)
