The Time Traveler's Fool

In a dialogue over six days between a psychiatrist and a man claiming to be a time traveler you decide if he is a lunatic, a time traveler, a murderer, a victim, all of the above or none. Start reading convinced that he is insane and end satisfied that you were right all along. Start reading convinced that he travels through time and end satisfied that you were right all along. Then begin the endless discussion with yourself or others about how both readings can be right or must be wrong.
Whoever he may be he is an articulate weaver of tales hilarious and horrible which include writing love poetry in the body of a shepherd boy wooing his first love, leading a small group of would-be legionaries in the body of a commander who has gotten them into a royal mess in the desert, fleeing a lynch mob in the body of a slave who may have been better off before a helping hand (or mind) and much more.
The Time Traveler's Fool is a rollicking good read but the reader who cares to dig deeper will also find serious literary themes of reality, perception, identity and the unintended consequences of good deeds.
