’Tis the season for mischief and murder in the eighth Year-Round Christmas mystery from national bestselling author Vicki Delany.
It’s Christmastime in Rudolph, New York, which means it’s time for the December Santa Claus parade. This year, shop owner Merry Wilkinson has decided to decorate her float as Santa’s elves’ workshop and invites her landlady, Mabel D’Angelo, to help supervise the excited children playing the elves. But when Mrs. D’Angelo doesn’t show up, Merry begins to worry.
Worry quickly turns into frustration when Mrs. D’Angelo reveals she was delayed by new neighbors moving in. As the center for all things gossip, Mrs. D’Angelo is determined to introduce the new arrivals to the neighborhood. As the days pass, Mrs. D’Angelo notices strange things about the newcomers, but Merry, busier than an elf in Santa’s workshop, has little time for matters that really don’t concern her. But things turn from jolly to downright concerning when Mrs. D’Angelo disappears and Merry is forced to admit that something might be terribly wrong.
With family and friends counting on her during this stressful holiday season, it is up to Merry to make sure this Christmas doesn’t end up wrapped in blood red.
Dollycas’s Thoughts
Rudolph, New York, is the place to be for Christmas as the town goes all out to welcome tourists to America’s Christmas Town. The shoppes are already seeing a surge of customers, and all are looking forward to the December Santa Claus parade. Noel Wilkerson is all decked out in his Santa garb, and Alan Anderson is on hand as his favorite elf, while Merry Wilkinson’s float is filled with children playing the roles of elves. The old person missing is Mrs. D’Angelo, Merry’s landlady, who was supposed to help with the children.
After the parade, Merry learns Mrs. D’Angelo was waylaid by new neighbors moving in. The Gossip Queen of Rudolph was set on being the first one to welcome the new people to the neighborhood, but before she could, she noticed some weird happenings at their home. She tries to get Merry to help her make a grand introduction, but Merry is swamped with work as the holidays get closer.
Then Mabel D’Angelo goes MIA, and Merry realizes maybe those new neighbors are something to worry about. Can she find The Gossip Queen and do everything else she needs to get done for everyone else before Christmas? Well, she sure is going to try. Hopefully, she isn’t the next Rudolph resident to disappear.
It is wonderful to visit Rudolph, New York, to catch up with the Wilkersons and their friends at the height of the Christmas season. They always have a lot going on, but there is always time to solve a mystery or two.
All the characters are well-crafted and developed. I enjoyed that Mabel D’Angelo played a major role in this story, taking what she usually does to a new level and landing herself in a heap of trouble. Mattie’s doggie love for Detective Diane Simmonds always makes me smile. I was also happy to see he made a new friend.
This time, we had to delve into a bit of town history to get the investigation rolling. A few people surprisingly end up on Merry’s suspect list when a past relationship is revealed. But Merry did make some mistakes as she tried to follow the clues; she knows better. That being said, I pegged the guilty party with ease early in the story, but the take-down was very entertaining. I loved that Vicky made an epic entrance.
There is a subplot about the town of Muddle Harbor’s failing economy. Noel seems to have some ideas to help the nearby town. I am intrigued to see where Ms. Delaney takes this.
I love the holiday atmosphere in Rudolph that rings throughout the story. The town is filled with people with big, generous hearts who breathe love in America’s Christmas Town year-round, and for other holidays too. Santa is never far away.
O, Deadly Night is a delightfully merry addition to the Year-Round Christmas Mystery series with a little murder and mischief to shake up the holidays. Sure to get you in the Christmas spirit. Bake up some Molasses Spice Cookies (recipe in the book), make a hot beverage, and sit back and escape to Rudolph.
