The Lost Treasure Map 6

A classic high quality action-packed treasure quest thriller of a London detective agency searching for ancient lost treasure.
Private investigators of a detective agency search for lost treasure after the discovery of an ancient map on an old piece of parchment and tales of it leading to lost treasure.
The investigators are fanatical with hunting and discovering what is there and the lost treasure, and they explore what they can, in a remarkable detective adventure.
They find strange mind-bending ghostly energy formations, witnessed haunting the region, which they have never heard of, even after consulting the most advanced paranormal scientists, and one gains strange magical-like powers.
The riddles are almost unsolvable, and their investigations with the paranormal scientists lead them to use a new highly advanced technology to search deep beneath the site, and discover far more than they expected.
The source of the occurrences is found deep underground, where they discover one of the strangest ghostly energy formations encountered, hidden away for centuries, in alternating dormant states, trapped in reality, and discover the lost treasure of a queen.

Workmen constructing a new section of the London underground near London Bridge during the Second World War uncover a large underground cavity and a workman discovers an ancient map on a tattered piece of parchment inside, which he believes leads to lost treasure, and he hires the detective agency to search for it, before the railway company starts filling in the cavity to complete the railway line, and while they do they investigate sightings of ghostly formations and a killer Santa, and they bring in archaeologists to excavate the cavity and they find the remains of an underground Roman burial site.
Leading archeologists are brought in to excavate the site and discover why it is buried away there, so deep beneath the ground, and start digging up what they believe are unknown prehistoric creatures, but soon find they are far more, and they find strange unknown species of life forms, frozen in strange states, as though frozen in ice.
Scientists unsuccessfully scan below the ground, searching for what is below, but while using a new form of the scanning technology they uncover things that never showed up on the original scans, and realize something below is stopping them from seeing what is there.
Something strange is buried deep below, hundreds of feet below, at least thousands of years old, and a blurred image of it is detected, and after examinations of it they grasp its immense size.
Eventually a tunnel is located, of Roman origins, going straight down towards it, and where the treasure must be located!
