The Interdimensional Detective: Cover Up by Ten

Ava Brooks has been whisked away through time and space by The Detective, and they've got their eyes on a sightseeing getaway (or at least, The Detective has). But when a call comes in to solve a mysterious murder that the police are covering up, that plan goes awry. Will Ava survive the insanity of a new world, or will she and The Detective drown in infinite possibilities?
