Once a murder has happened, to go back in time and prevent it might seriously mess with the timeline, and that is where the Time Patrol's Murder Squad comes in. They try not to kill anybody themselves, except in emergency defence of themselves or the timeline, but they are known as the Murder Squad because they are there to make sure the murders of the past happen.
Created in the far future, then sent through a temporal rift to the ancient past by the Chronomage Cara, the Circlet is an artefact designed to focus a mage’s energies when attempting to manipulate time.
A man was killed somehow and brought back to life. He, uniquely, remembers everything about Death, from the skeleton on the horse that guided him, to the afterlife itself. And the annoying bit where he was wrenched from his jacuzzi. He now has penned the instant best seller, entitled 'To Death and Back: My adventurers beyond the grave.' OR IS IT? Is this man telling the truth, or simply a very good liar? Is it all a fraud?
