THE SULLIVAN DETECTIVE AGENCY DOUBLE TROUBLE THE FINAL CLUE (PART-III)

Carter and Cooper Sullivan, identical twins with a talent for trouble, are convinced that their unassuming junior high, Bloomfield, hides a secret. Whispers circulate about a hidden basement and, more thrillingly, evidence of a mysterious sarcophagus. When they finally uncover the entrance—a locked door leading to a secret staircase—they enlist their adventurous friends, Brody and Kylie, to investigate.

To their surprise, their eccentric, retired Irish detective neighbor, Mr. Amos Murphy, catches wind of their plans and insists on joining their expedition with his old partner and friend, Tom Connor.

But uncovering the sarcophagus is just the beginning. What rests inside? Is it a genuine ancient artifact or an elaborate prank? And why is someone, or something, trying to keep them from uncovering the truth?

Bury yourself in this mystery as the final clue unravels the truth behind this odd missing mummy case. In this exhilarating tale, the twins and their friends must solve the enigma before danger wraps around them.
