Why has a ring with a diamond the size of a monkey's eye suddenly disappeared? Will it be found before the wedding party turns into an angry mob? Most importantly, can somebody get Joe Sherlock out of the bath in time?

Baskerville's only kid detective will have his brain squeezed in the pressure cooker of his neighbor's mixed-up wedding day. Joe Sherlock is ready for the challenge...as long as nobody offers him an egg salad sandwich.
