I give this 2.5 stars generously rounded up, but make no mistake it's a 2.5 star read. It's not bad, just ordinary, average, cozy mystery. Erin Gilbert runs a home decorating company in a town in Colorado, not far from Denver and with a mountain view. She's been hired to de-clutter the charming vintage cottage of an elderly woman, one that takes 'clutter' to hoard levels. Elderly Helen believes that someone not only is regularly breaking into her house and stealing her treasures, but also that someone murdered her sister who was living with her 3 months earlier, a death written off as an accident. Gradually not only does Erin begin to believe Helen, but another suspicious death occurs in the house and to someone closely connected to Helen.
The plot has its good moments such as Helen moving into half her garage to feel safer, some interesting developments especially deep into it, I wasn't really all that charmed by it. It seemed pretty average, with the villain way too obvious from the first meeting although the ins and outs of why were not. There were a few too many plot points that just ended where a little post-resolution narrative would have been welcome. There's also a side romance for Erin with her (male) competition, Whose last name is Sullivan (and yes the Gilbert & Sullivan joke is a tepid part of the plot) which is clearly on an 'off' cycle during this particular series entry, one that I didn't find particularly compelling. Maybe if it were not a rather stereotypical and shallowly presented heterosexual one, it would be more effective.
This is the 4th in the series, I've read none of the others and it worked just fine as a standalone. I think I have another in the series set at Christmas which I will read at some point but more? Probably not.
