Death of Innocence: an Al Pennyback mystery

Leana Sonnenberg didn't usually accompany her writer husband, Jacob, on his trips. Then, the one time she does go with him to a vineyard in Northern Virginia, she disappears. The local police don't have a clue, so Jacob hires Al Pennyback to stick his PI nose into the case. Al finds himself looking into everyone's background, and what he finds is far more deadly than he thought--and, it has nothing to do with wine.
