Clued to Death - White House Dollhouse Mystery series, #3

Olivia Reynolds, owner and operator of the White House Dollhouse Store in Minneapolis, attends a National Park expo at the Xcel Energy Center as a vendor and as a fan. Liv leaves her employee, Gina, at the First Lady Dollhouse booth while she attends the opening ceremonies. Gina drinks a beverage meant for Liv and dies. Liv is beside herself. Someone has murdered her friend and employee and now it's up to her to figure things out.
Enter an old land title, which may or may not have belonged to Teddy Roosevelt, a couple of assaults, a deranged murderer, and suddenly Liv has her hands full. Entertaining, informative, and always fascinating. Schlichting delivers another Teddy bear hug of a mystery!
