The Secluded Village Murders by Shelly Frome

They want to develop the hilltop above their bed and breakfast and they are trying to buy everyone below it out.  Emily has no desire to sell the bed and breakfast.  Her mother is thinking maybe they should and go elsewhere to make more money.  Then Emily's best friend who is like a father to her falls from a house he re-roofed.  He never regains consciousness and passes away.  Emily thinks he was murdered...

BQB Publishing and Net Galley allowed me to read this book for review (thank you).  It has been published and you can get a copy now.

It gets worse.  She's going on a tour with three folks from the village.  They are related but don't get along.  One of them even leaves early.  Emily knows something strange is going on but no one will admit anything.  Then the older one of the group ends up dead on the tour.  She can't get the cops interested in the deaths so she works on finding the killer herself.

Her romantic interest at home knows how her friend died but doesn't tell her because he doesn't want to upset her.  She's still upset and even more so after she finds out the cause. Her ferreting brings her to close to the truth and she almost becomes the next victim.  

There are plenty of suspicious characters, odds and ends of clues to check out, and the killer surprised me.  Did you guess right?
