Inspector Ghote embarks on one of his strangest cases when he is ordered to prevent a murder - the killing of a precious flamingo in the Bombay zoo.

And then there is the racehorse fancied to win the local Derby, which gets replaced by a donkey...

Ghote finds things going disastrously as bit by bit he unearths the traces of a monstrous practical joker. But then the fun stops - and Inspector Ghote has a more serious murder on his hands.
