@mchandra, I think I remember that movie there are 3 couples in total and the ones trying to return the dachshund are Julian and Phoebe who found it in rome and so they met and they meet two more couples and then they find the owner of the dog dead and the three couples are the main suspects, the roulette is from the casino in monaco where Neil is playing he is a compulsive gambler looking to win something big, the ticket and the amount that is to his left must be the reward that the owner of the dachshund would give him, I love crime and mystery movies
