A clue is a single piece of information that can suggest a lot of things if you make the effort to find out what it might mean. When you put separate clues together you can get even more information.
Clues separately (CS)
You examine each clue as if with a magnifying glass in order to extract the maximum amount of information from it. You should try to think of all the possible things that it could mean.
Example: A watchdog kept in a house was not heard to bark during the night of a burglary.
Examined by itself, this clue might suggest:
* The dog was asleep.
