Tanner 01: Rogue Agent

PORTAL
The Agency for Temporal Research operates a solar observatory in the distant past, providing valuable information about the sun's earlier history. But the unmanned observatory has shut down. Shielded, reinforced power lines have been found neatly cut apart.
With it's reputation at stake, the Agency sends Tanner to investigate.

RAIDERS OF THE SCROLLS
The Agency for Temporal Research has been asked for something a little 'unusual'. Scholars want them to save some scrolls from the ancient Library of Alexandria.
Dennis Tanner must raid the Library before it is burnt to the ground and the contents lost forever. Sounds like an easy mission for once - but he's been wrong before.

ROGUE AGENT
Stearman was a long-term colleague of Tanner's, but now he has disappeared in 10th century England. His mission has run to a stop and Stearman is nowhere to be found.
The past has its dangers, and more than one time traveller has disappeared without trace. Occasionally one has gone rogue, and then Tanner or one of the other field agents is dispatched to restore order to the timeline.
Is Alex Stearman lost, injured or dead ... or simply in hiding?
