The Three Coffins

 The Three Coffins (The Hollow Man; 1935) by John Dickson Carr

Eccentric Professor Charles Grimaud, a student of legends and the supernatural, holds court regularly at a local tavern. He and his circle of friends discuss vampires, werewolves, ghosts, and the like--debating their reality and the sources of their legends. One evening a stranger bursts into their gathering speaking in a bizarre, somewhat threatening manner. He talks of men coming up out of their graves. He says that he has come out of the grave.

Yes, I have done it. But more! I have a brother who can do much more than I can, and is very dangerous to you. I don't want your life; he does. But if he calls on you...

and later in the conversation

I have a last question for the famous professor. Some one will call on you one evening soon. I also am in danger when I associate with my brother, but I am prepared to run that risk. Some one, I repeat will call on you. Would you rather I did--or shall I send my brother?

The professor tells him to send the brother.  

And several nights later someone does call upon the professor. And apparently he did want the professor's life. For when the night is over, Professor Grimaud is dead--shot to death in a locked room by a visitor who vanishes into thin air.

When Dr. Gideon Fell is regaled with the story of the tavern scene and learns that the visitor is expected that very night, he immediately gathers Ted Rampole (teller of the tale) and Superintendent Hadley, his detective friend, and insists that they make tracks for Grimaud's house. They're just in time to be told that there has been the sound of a gunshot and that the visitor is locked in the professor's study--with the professor. They manage to gain entrance and find Grimaud mortally wounded but the visitor is nowhere to be seen. The window is open, but there is a yard full of unmarked snow and no way to go out the window to the roof or another room. 

Fell and Hadley and company have just started investigating the first impossible crime when another occurs. This time it is Pierre Fley, the man who confronted Grimaud at the tavern. And he was shot in the middle of a snow-covered street at close range. But three reliable witnesses swear there was nobody else near the stricken man and a voice came out of nowhere that said, "The second bullet is for you." Now our detectives have to figure out how the two men were connected and who wanted them both dead....oh, and, of course, the trifling little matter of how it was all done.

Carr works his locked room/impossible crime magic and comes up with a solution that I had to think about twice. There was one moment where I thought--but if X was going to do what Fell said he was going to do, then why did he need that? So, I had to go back and reread and then the light bulb went off. Oh, yeah. That's why. This is also the book that has the famous "locked room lecture" where Fell tells us straight up that he knows he's in the middle of a detective story and then goes on to explain the various ways to commit a murder in an apparently locked room. Naturally, he doesn't list the ways these two particular impossible crimes were contrived.

I have to admit that I was on the side of Hadley during this particular reading (I read this once before back in the mists of time--but it was long enough ago that all the details had dropped out of my head). I was a bit restless during the Fell lectures and just really wanted to get on with the story. But the impossible crimes are quite good and I enjoyed finding out how it was all done. [Though I have to say I could think of a better way for a certain item to have been hidden that would have been far less disastrous for the person doing the hiding...]. And other than when he was in full lecture mode, I enjoyed Dr. Fell and watching him go to work. This also has one of the better dying words clues among those I've come across. Quite good fun. ★★★★

First line: To the murder of Professor Grimaud, and later the equally incredible crime in Cagliostro Street, many fantastic terms could be applied--with reason.

"I am a mathematician, sir. I never permit myself to think." (Stuart Mills; p. 30)

In my experience with locked-room murders, getting in and getting out are two very different things. It would throw my universe off balance if I found an impossible situation worked both ways. (Superintendent Hadley; p. 46)

Last lines: "I have committed another crime, Hadley," he said. "I have guessed the truth again."
