Puzzle #2 for April, 2008 “The Lady or the Tiger?”:

Solution to #2

You are presented with two doors. Behind one waits a lovely lady with a bag of gold. Behind the other crouches a hungry tiger. If you pick the right door, you get the lady with the gold. If you pick the wrong door, you get eaten.

There are signs on the doors, one of the signs is true and the other is false.
The sign on Room One reads:
IN THIS ROOM THERE IS A LADY AND IN THE OTHER ROOM THERE IS A TIGER.
The sign on Room Two reads:
IN ONE OF THESE ROOMS THERE IS A LADY, AND IN ONE OF THESE ROOMS THERE IS A TIGER.
With that information can you chose the door with the lady?

Puzzle #3 for May, 2008 “The Politician Puzzle”:

We are given the following two additional facts:
    At least one of the politicians was honest.
    Given any two of the politicians, at least one of the two was crooked.

Puzzle #4 for June/July, 2008 “The Case of the Grandfather Clocks”:

Solution to #4

Arthur and Robert were each in charge of a beautiful antique clock at a Museum.
Both were born in the month of May, one in 1932 and the other a year later.
Both of the clocks worked well but one of them lost ten seconds an hour and the other gained ten seconds an hour.

On one bright day in January, the two friends set both clocks right at exactly 12 noon.
"You realize," said Arthur, "that the clocks will start drifting apart, and they won't be together again until the very day you will be 47 years old."
Robert then made a short calculation. "That's right!" he said.

Who is older, Arthur or Robert?
