Bound for a remote planet on the far side of the galaxy, the crew of the colony ship \'Covenant\' discovers what is thought to be an uncharted paradise, but is actually a dark, dangerous worldâ€”which has a sole inhabitant: the \'synthetic\', David, survivor of the doomed Prometheus expedition.
The scene of the crime is Whitechapel, the same London district notorious for the recent attacks of Jack the Ripper. Three monks are found dead, the apparent victims of a vampire - now, someone else is out for blood. Or is it something else? As bizarre events unfold, the answer is left to Sherlock Holmes and Dr. Watson to find.
