Time Gentlemen

"When two deadbeat brothers accidentally steal a time machine, the consequences have already happened. Or will happen. Or will have been happening. Look, just read the book will you? It'll be easier on the both of us. I'm going for a lie down."
The Adventures of Jack and Joe is a science fiction comedy featuring private detectives Jack and Joe. Time Gentlemen follows the exploits of our heroes as they travel back and forth through time and inadvertently save the human race.
Along the way they get themselves in trouble with the police, prevent the assassination of a world leader, discover a virtual world, make a robotic enemy, rescue a naked woman, make a rival detective envious and track down a missing cat. And all the while people keep trying to kill 'em!
And best of all there are no loose ends! Probably*.
This is Craig P. Kelly's first novel. He thought it was a good idea at the time.
*Absence of loose ends is not guaranteed.
