A collection of short stories, revolving about time travel. With links, sometimes very faint. Then, time travel and cause-and-effect have interesting relationships here.
The first and last are told in achronic order, which suits them well. We have mysteries, attempts at rescue, and the effects of time travel and cause-and-effect on interactions. A private investigator who observes that, in fact, a trenchcoat and fedora are normal attire where he comes from. A widowed bum. The fates of those whom the Time Wardens are no longer interested in but don't let leave. And more.
