The Case of the Murder at the Butler's Convention

A tragedy occurred at the 47th Annual Convention of Butlers at the Highland Hotel. Al Weicker, president of the butler’s association, was found shot to death in his room. Detectives Davis and Moreno soon arrived at the scene.
“This might not be easy to solve,” Moreno said. “Since most of the possible suspects are butlers. We don’t even know for sure if a butler did it.”
“We’ll just have to do the best that we can with the facts in this case,” his partner replied.
Davis surveyed the scene of the crime. The body of Weicker lay near his bed. He was in his pajamas. His clothes were neatly folded up on a nearby table. There was a large pool of blood on the floor.
“Did you see or hear anything suspicious?” Davis asked Cliff Epple, the director of security at the hotel.
“No, unfortunately this was the only floor where our security cameras weren’t working,” he replied. “However, we reviewed the tapes of the other cameras and found that no one left this floor after the murder. We strongly suspect that the culprit is a guest on this very floor!”
“That may help narrow our list of suspects,” Moreno said. “We shall begin our investigation immediately.”
Davis asked each person on the floor, “Do you have any information about the murder of Al Weicker?”
Ben Lagenvist shook his head. “I’m sorry. I don’t know anything about it. I was shocked to hear of it. It’s a terrible tragedy.”
Dave Hastings said, “Sorry, old boy. I haven’t the foggiest idea. It’s been a most regrettable incident, I dare say. My good man, I do not think that any gentleman’s gentleman could have been involved in something like this.”
“Good Heavens! Someone was murdered, you say?” Lyndon Smythe-Jones exclaimed. “My word! What the devil is going on here? By jove! I dare say I shant sleep a wink this night.”
“I’m sorry, but I didn’t even know the poor fellow,” Joseph English replied. “I must have slept through the entire incident. Well, I sure hope that you find the dreadful booger who plugged that poor Alton chap!”
“Blimey! Heavens to Betsy! Murder? How dreadfully unsporting, I must say. No, I haven’t heard a thing about it,” Percy London said. “Now if you’ll excuse me, I must be tottering off. Cheerio!”
“I say, my good fellows, do have any clues?” Moreno asked his partner.
“Elementary, my dear chap,” Davis replied. “I do indeed. Right-O!”

WHO DID DAVIS SUSPECT?

THE ANSWER
He suspected Joseph English. Even though English said that he hadn’t known Al Weicker, he still referred to him as “Alton,” even though his name might have been Alfred, Albert, Allen, or just plain Al. A warrant was soon obtained and a search of English’s room soon turned up the murder weapon. A “jolly good show” for the detectives!
