The Case of the Nosy Time Travellers

Rachita and Aarti have a nemesis who is out to destroy them ...

Garbage vandals are defacing walls of residential societies. Aarti's birthday presents include miniature coasters. Rachita starts having egg-themed nightmares ...

Are these happenings related to the mysterious time-travelling detective gang that is challending the Superlative Supersleuths? And will they be able to foil their rivals or will they end up getting pwned?

Case notes:
1. Why do the eggs have banana heads?
2. The Harappans cared about home furnishings.
3. The Nemesis might be a time traveller!
