A pair of identical twin babies is a valuable clue in cracking a clever disguise.

This is by far the weakest of the Larry mysteries. The plot—and its solution—is rather convoluted and confusing, and I'm not entirely convinced of the solution. (The idea is that the woman pretending to be the twins' mother is actually their aunt on the lam, and she can’t pick up on the subtle clues that distinguish them while Larry can.)
