Coriolis Effect: an Ed Lazenby mystery

A straight line is not always the shortest distance between two points. Ed Lazenby knows that sometimes you have to aim at where your target's going to be rather than where it is at the moment. That was the last thing on his mind, though, when a neighbor he'd never spoken to before asked him to find her missing grandson. He was tired of people thinking he was a hero, just because he and his best bud, Ernesto Cardoza, had rescued their friend Violet Wertheim from kidnappers. But, he was also bored, so when Abigail Crumley came along with her request, he said yes. Ernesto, of course, went along for the ride-and, what a ride it turned out to be.
