In March 1882, when John Watson is invited to Edinburgh to visit his
cousin, the eminent Dr. Patrick Watson, he convinces Holmes to accompany
him on what he believes will be a relaxing holiday. But where Sherlock
Holmes tends to go, then surely a crime must be detected. What begins as
a chance encounter of a seemingly simple mystery at an Edinburgh home,
soon takes Holmes and Watson in to conflict with the Edinburgh Police,
an investigation involving murder and corruption, and crossing paths
with the local populace including Dr. Joseph Bell. As Holmes works more
closely with a young Edinburgh constable on the case, it causes Watson
to question not only his own position, but his very relationship with
Sherlock Holmes.
