"Sit down, Morgan," said the Chief, waving his hand toward a chair. "I've got a case here that'll make even you go some."
As Morgan sat down the Chief gathered up some typewritten sheets from his desk, and continued; "I didn't like to break up the first day you've had off in a long time, Morgan, but there was a murder on Sheridan Road last night—or early, this morning, to be exact—that has put a real mystery up to the Department. It'll need a man like you to solve it—if it can be solved. The newspapers had big headlines this morning, and the public will be watching us on account of the peculiar nature of the crime."
"I saw something about it in my paper this morning," said Morgan. "There were no details, however. The notice probably caught the last edition with little more than the fact that a murder had been committed."
"Well," exclaimed the Chief, "it's one of the biggest mysteries we've ever had handed to us. The shot was heard by both the man on the beat and a tenant in the building, but outside of the stories of these two men, and the discovery of a blood stain on a rug in a supposedly empty flat, not another thing has been found. The body is missing, and there is no trace of how it got out of the flat or where it is now. Here is a report of all that we know so far. By the way, your partner Tierney made this report. He happened to be on the job last night, so I told him to stick to it."
The Chief handed the typewritten sheets to Morgan.
"You will note," he went on, "that the man on beat heard a shot at about 2 A.M.; that he met a tenant from the house who said that he had heard sounds of a struggle, a shot, and something like the falling of a body. The police found the flat locked, and after they broke in could find no one on the premises. Nothing was upset, and there were no signs of the struggle, said to have taken place. Another peculiar thing is that the police even overlooked the bloodstain until the tenant who had heard the shot called their attention to it. Tierney tried to get some more details this morning, but you will find from his report that none of the other tenants admit hearing the shot; that the tenant in the flat across the hall was apparently not at home, and that the janitor says the people who rent the flat in which the trouble occurred, have been away all summer. The only really definite information of any kind comes from this one tenant, Marsh."
"You'll probably find Tierney at the flat, as I sent him back after he had turned in this report. He may have found out something more by now than he could put in that quick report."
"Chief," said Morgan, as he thumbed over the typewritten sheets in his hands, "you say there has been a murder committed here. With this tenant, Marsh, and a patrolman, getting into action so soon after the shot, a body couldn't possibly be moved out of the house—certainly, not without leaving some trace."
"Well?"
"How do we know there was a murder?"
