First-time author Craig has the genre down pat in this smooth debut novel featuring Martha's Vineyard fisherman (and ex-big-city cop) Jeff Jackson--who, while teaching spunky nurse Zee Madieras to cast, sees the Nellie Grey explode. The explosion kills likable transient Jim Norris and injures ex-druggie Billy Martin, whose super-rich dad George has another heart attack when he learns of the mishap (his nitro pills don't help him, for some reason). Did someone want to kill Billy, who might have been planning to squeal on his former drug connections? Or was Norris, for reasons unknown, the mark? Jeff's investigation turns up a bored housewife-dealer, with a yen for young men; Billy's current career as a pusher at Brown University; and Norris' real father--a Vineyard resident--before he's shot at, then rescued by a perfect cast from Zee. The culprit escapes, as does the drug dealer (who later kills him), and Jeff compassionately declines to tell Billy's family the whole truth about Billy and his greedy reasons for exploding that boat, instead letting them believe he was a hero/victim. A neat, twist ending as well as a commendable mingling of past and present mysteries. Low-key and appealing fishing lore, but too many bluefish recipes and too much emphasis on cooking. Still, a nice series beginning.
