That well-known archaeologist and little-known poet, Cairo Jim (assisted by Doris the macaw and Brenda the Wonder Camel) is on the trail of another mystery!

When the manicured evil genius, Captain Neptune F Bone, disappears in the Red Sea while diving for a lost sarcophagus, Cairo Jim and his friends are called into try and help find him in the dark and watery depths.

But when Jim, Doris and Brenda take the plunge, little do they know that what they are about to find will become one of the most flabbergasting discoveries in the history of archaeology.
