This improv game is in the following improv game categories:
The cops interview her best friend, suspecting him to be the killer. The audience gets to pick the player who will play the best friend.
Audience also provides the names for both characters, and indicates how long the 2 have been best friends.
The performance itself is a game of ping-pong between interrogation of the friend by the cops, and flashbacks.
Performance starts with the interrogation. A question might be "How long have you been friends, and how did you meet?" The scene then jumps to the moment the characters met.
When the scene is over, we switch back to the interview. We may now be at a different moment in time - the idea is that we see bits and pieces of the interrogation, at various points in time. The friend can indicate time as in "of course I am happy to help" or "OMG how did she die?" (indicating time right after the murder). Or say "this is the tenth time you bring me in", or "I've been here for 3 days now. Am I under arrest?" - indicating a later time. There is no need to go chronologically in the interviews.
Every interview question leads to a scene, based on the information provided in the answer to he question. The scenes need not proceed chronologically - feel free to jump around in time.
Performance ends when the cops ask the question "Did you do it?". Before the friend can answer, lights go out. We will never know; we never see the actual murder either.
