Showing How I Spent My Summer Vacation by Gillian Roberts

Amanda Pepper's friend Sasha has a photography assignment in Atlantic City, and she invites her broke schoolteacher friend to come along for a free mini-vacation. But the two quickly discover there's more to lose than money at the shore when Sasha finds a stranger bludgeoned to death in her bed. When a witness identifies Sasha as having been at the scene, she Goes Directly To Jail and does not pass "Go." Under the boardwalk and between the slot machines, and sometimes with the help of a motley crew of gamblers, Amanda works to unearth the truth and free her friend.
