I loved, loved, loved this book! Kate Sharp is looking forward to a quiet weekend with Alex, her boyfriend, and his 12-year old sister who is coming home during her boarding school break. Alex has custody of Grace after issues during their parents' divorce. However, Kate gets a phone call from Elsie asking her to go to the Parkview Regency Weekend instead and cover it for their upcoming documentary on Jane Austen. And Kate gets a couple of messages from Beatrice the Lady of Parkview Manor who needs her help.
Kate makes her apologies to Alex, especially when it seems like Grace would rather spend time alone with her brother, and heads to Parkview. She finds out from Beatrice that someone is posting attacks on Parkview Manor, and Sir Harold on the couple's social media accounts. Beatrice realizes from the posted pictures that whoever is behind the campaign must be on staff and asks Kate to look into it. Kate accepts the assignment.
Kate also meets the other guests for the weekend - a bridal party who booked the weekend so they can plan the bride's wedding, a young man who is researching a book on butterflies, and Victorian butterfly collectors/collections who want to research the collection at Parkview, a wealthy couple - he's a corporate bigwig and she's a spoiled socialite who was always in the tabloids before they married, and Jo and Simon - both of whom turn out to be hiding who they really are.
When the corporate bigwig is murdered overnight, Kate is embroiled in another mystery.
The first morning of the Regency Weekend Kate is awakened when by a very upset maid, Ella. Kate checks it out and discovers that Toby Clay the corporate CEO is dead and his wife Monique is still asleep beside him. Soon guests are milling around and the police are called. But who killed Toby when the room door was locked? Ella, the maid, had to unlock it to enter the room. And the glass door to the balcony is also locked.
Kate begins to investigate not only who is posting hateful messages on Parkview's social media websites - but who killed Toby Clay. Kate returns to her room in the afternoon only to be assaulted by Simon. Simon accuses her of murdering Toby, even though Kate didn't even know him and had never met him before this weekend. He threatens her with a taser and demands the police arrest her. He also claims to be a PI hired by Sir Harold. Kate points out that Beatrice (aka Lady Stone, Harold's wife) asked her to look into the social media attacks. Fortunately, the DCI on the case believes Kate and thinks Simon's wild stories and accusations are just that - wild fantasies.
Kate continues to look into things and does discover who on the staff is sending the "poison pen" letters and why. Beatrice explains to the young woman that she and Sir Harold did not kick her grandmother out of one of the cottages on their property that they turned into vacation cottages. They actually paid the woman quite a lot of money. However, she was then taken advantage of by a con artist who stole everything from her. Even then Sir and Lady Stone had offered her the cottage back and the old woman refused. The young staffer is agast and even apologizes for her behavior.
Kate meanwhile has called Alex a few times to see how his weekend with his young sister Grace is doing. It seems okay, though Grace is a bit moody. Also, the weather turns nasty with a lot of rain which makes outdoor activities difficult. In the middle of a heavy thunderstorm, Grace shows up at Parkview. She's soaking wet and upset. Grace explains she decided to go to Parkview after all and got caught in the rain. Kate takes care of her, drying her off with towels and having Ella find her some dry clothes. Kate calls Alex to tell him Grace is at Parkview and reaches a panicking Alex who says Grace has disappeared. However, before Alex can get to Parkview the river floods the bridge, and Parkview is cut off. Kate tells Alex she will look after Grace. The DCI is also not at Parkview at the moment because he's dealing with the aftermath of finding the person responsible for the social media attacks on Sir Harold. So now, Kate and Grace are trapped in a country house after a murder.
Grace, however, loves it - feeling like she's in an Agatha Christie novel come to life. Slowly, secrets are revealed - we find out who Jo really is. Simon claims to be a PI. Grace discovers the guy writing the book on butterflies isn't who he said he was either. Grace also helps Kate figure out who else was in Toby's bedroom the night of the murder and how they entered a locked room. Finally, it's Kate who figures out who the murderer is and they are turned over to the police.
I loved this book. Kate, Grace, Beatrice, and Alex are great characters - but the guest characters in the book are awesome too, especially Ella, the maid (who had worked at the local pub but was aspiring to be an actress and figured a weekend of historical reenactment would be good practice). The story combines a classic locked-room mystery - with some great reveals and a classic manor house mystery. I loved how the weather and rising river wear woven into the story so it didn't seem like a convenient shock when Parkview was cut off. And the final solving of the actual murder was good too. Plus, as in all good mysteries - everyone has their secrets, all of which are revealed. I highly recommend this series and Death in a Stately Home in particular. I've ordered the rest of the series and I'm eager to read them all!
