Stalked by Death - Judith A. Barrett - Bog

Riley Malloy, vet tech and dog whisperer, suspects her father's death seven years ago was not an accident. The killer waits for an opening to kill Riley.
Riley is the only person alive who can solve long-ago murders and expose the crimes of an international ring. Complication: Riley doesn't realize the significance of her grandmother's letter or the documents she finds or how desperately her unknown enemy watches and waits for the opportunity to destroy the evidence and kill Riley.
