(8:12 PM Stolen Vehicle Call) Officer Philip Mercurio got his K-9 Louie on 12/22/89 out of a dog pound at the Humane Society. He's a Rottweiler and he trained him for 4 months. The first time he saw the dog go after someone on the street for going after him and it was amazing. You get attached. He's seen two K-9 men lose their dogs. You see grown men crying over a dog and it's strange, but now he understands the attachment. He chases a silver Mercedes Benz on Clarissa St. Traffic gets in way and he yells. It's a personalized plate. They bail out on foot and give chase. He tells Louie "good boy" over and over. They catch a young black guy near a bunch of cars. Phil says if he moves he'll break his head open. The other got away beside the hospital. They make the guy lie down and run out to the street to look for the other guy. He tells a guy to watch him and goes over to the next guy who is caught by a civilian behind the Atlantic. Four guys were in the car and two were caught. The guy had to jump on the car to get away from the dog, he was proud. (11:24 PM Street Patrol) Officer Thomas Harris says the ladies of the evening are out. They are going to disperse them instead of arresting them. The area of the hill is heavy with whores. He spots a girl who tries to hide who would rather be arrested than get a lecture. They run from him hard to avoid lectures. He talks to a woman who says she's waiting for a bus. There were whores around who moved on and she's not working. She's a diabetic and can't use drugs. He knows the prostitutes and hasn't seen her before, if he sees her again he won't buy it. You can fool him once, maybe twice. Tom says two cars just checked her out. Leon pulls up and they don't recognize her. She lives in Liberty, but can't say which street. She does have ID though. He asks where her carfare is. She doesn't understand and says she has a bus pass. She digs around for it and he says he's had checks come faster in the mail. She keeps looking and can't find it. He says she played him and she wants her tissues back. He says he doesn't want her snot rag and will engrain her face into his brain. He would rather she told him the truth and he wouldn't have arrested her, but she danced around him like Ginger Rogers. She says she stays at East Liberty, but was staying with her nieces. She finally admits she came out there to work. His head is spinning, he's insulted. (11:40 PM 911 Call) Officer Joe Arroyo first started working at the jail when there was a full moon and there were lots of suicides and attempts. On the streets it makes people nuts, usually they are nice. They go crazy, he believes in it. Some people think they are crazy, but ask doctors or nurses in the ER and they'll tell you. It's a full moon tonight, so we'll see. Communications Center - Charles is on the 6th street bridge threatening to jump off. He has a history of alcohol abuse and wants his sister to come to him so they call her. Anthony Novak, a Paramedic from the Pittsburgh Fire Department talks to him. Charles gives them his mom's number in case they can't get the sister. He's way up high on the top of the bridge. He says no one cares so why should Officer Jean White care who is helping. Commander Robert McNeilly arrives. Jean has known him since they were kids. She tells him Mary Lou is on the way down. He wants to see his dad in heaven. They are sending a car for his sister and it takes time. Mary Lou arrives and is hysterical. She tells him please come down, please, talk to her. They tell her it's really wide up there, he didn't jump. There are a lot of birds up there making noise. She tells him she loves him, Carol loves him, Crystal loves him and to come down. Mom loves her. He asks if she wants him to jump. She says no. They won't touch him if he comes down, they'll just take him to get help. He starts coming down, doesn't remember climbing up there, he was drinking and sobered up when he got there and was scared to climb down. He didn't want the fire ladder. She hopes the next time she sees him he'll be happy like he used to be.

While Poirot attends a fancy dress ball as himself, he is asked to investigate the killing of Lord Cronshaw.
