Two Fuses

You have a lighter and two fuses that take exactly one hour to burn, but they don’t burn at a steady rate. For example, one fuse could take 59 minutes to burn the first inch and then burn the rest of the fuse in the last minute.

How would you use these two fuses to measure 45 minutes?

Light the first fuse on both ends and the second fuse at only one end. When the first fuse burns out you know 30 minutes have passed. Light the other end of the second fuse and when it burns out, 45 minutes have passed.

Dead At The End of An Alley

A man is found dead at the end of an alley. A detective who enters the scene sees the letter X and immediately knows who killed the man and why. What did the detective conclude?

The alley is a bowling alley. The man who was killed was a pin spotter (an old profession where they would reset the pins by hand). The X was the marking on the score sheet for a strike. The detective saw the letter X and knew that the person bowled last, got a strike, and was due to bowl again. But they bowled before the pin spotter could get out of the way.
