Assignment 1: Find party responsible for murders by space virus. Assignment 2: Investigate 'accidental' deaths on orbital solar shield. Assignment 3: Apprehend criminal possessing short term time machine. Science fiction meets crime in this new anthology exploring one of the genre's most popular themes: mystery and detection. Pitching detectives against time paradoxes, alien intruders, AI gone bad and psychic mutation are ten stories embodying the exciting range of the sub-genre, rarely given the recognition it deserves in the literary sphere. With fascinating settings such as robot society, asteroid belt space stations and worlds similar to our own but uncannily altered, these stories are masterpieces of satisfying setups, memorable mysteries and timeless twists.
