Under Arrest - Van Gogh's Paris Road

Captain Jim Scott picks up the ringing telephone in his office and says "Captain Scott speaking". The voice on the line says "Captain Scott, this is the special guard at the Blake Art Gallery. I want to see you about the alarm you hooked up on the Van Gogh painting we are exhibiting". Scott asks "What's the trouble?" The voice says "I'd rather not say on the phone. It's very important". Scott says "Alright, Lieutenant Gavin and I will be right over here". The voice says "No Captain, come alone if you don't want to cause any unnecessary murder". Scott started to ring Lieutenant Gavin, but something about the voice told him that he'd better appear to comply with the instructions. As Scott drove out toward Stanchion Boulevard, he felt like laughing. Nothing exhibited in this city had ever been as well guarded as that painting. Van Gogh's painting, "The Paris Road" was on tour of the US as a goodwill gesture from a country whose goodwill we wanted. That's why the gallery had a special guard. That's also why we'd installed an electrical shocker alarm which could only be controlled from the police station. When he arrived at the art gallery, Captain Scott goes inside, and asks "You're the guard here?" He says "That's right, Captain Scott. Is there something I can do for you?" Scott asks "What was that phone call about?" The guard says "Phone call? What phone call?" Scott says "Look, I'm a tired man. Did you call police headquarters about ten minutes ago?" The guard says "No, I haven't called anyone". Suddenly, the art gallery phone starts ringing. The guard picks it up and says "Blake Art Gallery. Yes, he's here. It's for you Captain". Scott says "Hello?" The voice on the line says "Police Captain Scott, I'm glad you saw fit to do as I said". Scott asks "Who is this?" The voice says "That really doesn't matter. What does matter is that there are people in that room with you. Innocent spectators who might get hurt if you don't do exactly as I say".
