The Other Slab Tynan
The Squadron that Time Forgot
Night of the Ripper
Time Machine
Judge Death - The True Story
Dead Reckoning
Travels with Muh Shrink
Fog on the Eerie
The Strange Case of Bill Clinton
Whatever happened to Bill Clinton?
Generation Killer
Tempus Fugitive
Time and Again
Time's Squared
By Private Contract
Sure there's some that have escaped me, though.
