Simon Says… Believe by Dale Mayer

Detective Kate Morgan wishes all holidays were filled with celebration and joy, but her latest crime scene tells a different story. The leftover festive spirits of Christmas and the new year are overshadowed by the grim reality of another murder. No amount of ribbon wrapped around the body or notations on a greeting card to Believe can change that.
As she delves into the first murder of this year, Kate unexpectedly uncovers a second case—another victim and another instance of holiday cheer turned sour. Are these cases linked, or is Vancouver experiencing an unusually grim extended holiday season?
Simon stands by Kate, offering his unwavering support in her investigations, just as she stands by him and his architectural rehab projects and his peculiar psychic visions. However, when these visions and unsettling rumors begin to threaten his real estate business, Simon realizes more is at play …

But what exactly is happening, and is Kate involved in all this?
