Twin Stars in Shadow

The story takes place in a seaside city that retains a large number of old colonial buildings. The core suspense revolves around the death of an antique dealer: the scene is closed, but the key murder weapon disappears, and a pair of seemingly unrelated antique pocket watches are left next to the deceased, one of which has its hands permanently stopped at the time of death. The real suspense lies not only in "who is the murderer", but also in "why the murderer deliberately reproduced the methods of an old solved case". The unknown identity of the deceased collector in the past gradually reveals a grudge and entanglement spanning twenty years.
