Something Sweet

In the desert of coraltree, there is a little town named Wasser. It was a peaceful town. It was full of Good people. No conflict has ever taken place in this town, no criminals, nothing that brought bad omen to the town.
The peace in Wasser lived a long life. However, that peace was very flimsy so it was easily snapped.
On a silent night, a sinister figure with a gun appeared on the Wasser pub's roof. The sinister figure aimed and shot Annie Cassidy whilst she was asleep.
In the morning, people were drenched in fear.
The first crime in Wasser had taken place. It was chaotic. Sheriff Dylan, Detective Colton, and the entire police station are alarmed and bewildered by a single message written in gore. "Something Sweet".
Who is behind the murder? Is the question everyone had.
A question that may or not be answered.
Will Detective Colton solve this case and uncover the identity of the sinister figure?
Only time will tell.
