The Black Museum - A 32 Caliber Bullet

On a London street, a dark sedan with three young men inside, named Jack, Matty, and Rod drove slowly into the stream of traffic. Rod is the youngest, at only 17 years of age. Jack asks "You got everything straight, Rod?" Rod replies "sure, I'll stay in the car until you signal it's all clear, then I'll go in with you". A parking spot was found on the street near the jewelry store. Jack and Matty leave the car and start walking down the street. The jewelry store seemed very busy, so they walked past a few steps, then turned around to see Rod going into the store. Jack and Matty ran in behind him. Matty says "Rod, what's the idea? Rod says "you signaled didn't you?" Jack says "never mind, let's do it. All right everybody, this is a hold-up! Over against that wall! Everybody, these guns are loaded".
