No Place Like Home - Mary Higgins Clark

I cannot believe I am standing in the exact spot where I was standing when I killed my mother...When she was ten Liza Barton shot her mother dead, trying to protect her from her violent stepfather. The court ruled the death a tragic accident. Many believed it to be deliberate murder. Twenty-four years later, Liza is known as Celia. Now a successful interior designer, living in Manhattan, she is happily married for the second time, with a young son, Jack, by her first marriage. Nothing can disturb their peace. But when her new husband surprises her with a gift, her world is suddenly shattered - for it is the very same house where her mother met her death. It soon becomes clear that someone in the community knows Celia's true identity. And when the estate agent who sold the house is brutally murdered, Celia instantly becomes a suspect. As Celia fights to prove her innocence, she has no idea that she and Jack could be the next targets of a ruthless killer.
