The Wonderbolt — Paul Capon

Who would have thought that the innocent-looking object, rather larger than a golf ball, that landed in Pepe Hobin's garden in Tahiti could wreak so much havoc in its passage across the world? For this little meteorite, known as the wonderbolt, brings trouble to all who come into contact with it. Why, then, will men commit murder to gain possession of it? Is its acquisition really so desirable? Nat Spalding, private detective, is not sure at first, but later, much later, his thoughts on the subject are quite definite.

This is a fast-moving and ingenious thriller that crosses genres.
