In the second instalment of a charming mystery series, a Mumbai-based investigator and his elephant partner are on the hunt for the Queen of England's stolen Crown Jewels.

Now part of the British Crown Jewels, the priceless gem is a prize that many have killed to possess.

So when the Crown Jewels go on display in Mumbai, security is everyone's principal concern. And yet, on the very day Inspector Chopra visits the exhibition, the diamond is stolen from under his nose.

The heist was daring and seemingly impossible. The hunt is on for the culprits. But it soon becomes clear that only one man -- and his elephant -- can possibly crack this case. . .

Featuring the most charming crime-solving duo ever to grace the pages of a book, the Baby Ganesh Detective Agency series is a must-read for fans of Alexander McCall Smith.
