How about a SF murder mystery? Instead of recreating the crime scene, just rewind time to see the crime as it is happening. Only problem is time dilation. The person looking at the rewound time from outer space would age much slower than the culprit on Earth. We're talking beyond infinite aging and into a complex valued aging. That shouldn't be too big of a problem though. Since we already scrapped part of relativity to go FTL, might as well scrap the time dilation aspects of SR as well. Just declare that Newton was right after all, don't mention the mountain of evidence to the contrary (that's why it's called Science Fiction instead of Science Fact) and get on with writing the book.
