Portrait in Crime (Nancy Drew Summer of Love Trilogy #2) by Carolyn Keene

Case 49: Nancy goes in search of a missing painting -and uncovers a new twist in the art of murder...

Nancy's summer in the chic Hamptons beach resort is growing hatter by the day. She's seeing more of Russian dancer Sasha Petrov, and she's not sure if it's friendship or if it's love. Meanwhile, the new guy in Bess's life, waterskiing instructor Tommy Gray, has drawn her into a mystery of a more sinister nature.

Tommy's mother owns an art gallery, and a painting by one of her artists, Christopher Scott, has vanished. Scott's nephew died only a few days before in a suspicious accident, and now the artist himself is nowhere to be found. Was it murder? And if so, who was the victim?
