Fun with Cryptography - Cyptoquip

Recently, I found a puzzle called Cryptoquip in my local newspaper, the Toronto Star.

The basic premise of this puzzle is a simple plaintext encoded using a substitution cipher, of which one letter clue is given (i.e. Today's Clue: L equals S). Using this clue and the properties of the message itself, you must solve the puzzle. It requires some logic, some intuition and also quite a bit of luck (so be patient).

Strategies:
Look for one-letter words (they have to be "A" or "I")
Look for common three-letter words (i.e. "THE")
Use hyphenated words, exclamations and quotations to your advantage (e.g. a quotation may be preceded by a word like "SAY")
Cross-check your guess letters in multiple locations, when possible.

With a little practice, you can become a skilled code-breaker. The punny messages are great fun to crack and I have to say that I am already addicted.
