The author of the rather far fetched Indian Drums Beat Again with another mystery-adventure where two boys, by connivance and contrivance, manage to capture a mess of uranium thieves. On their way out to visit Aunt Ellie in Phoenix, David and Jack Sparks meet a suspicious stranger on their plane. Later another man wants to buy a mine owned by Aunt Ellie's father-in-law. Detection leads to danger, uranium and the kind of reward that isn't awarded many boys we know. Hard-cover pulp.
