Editing Unwritten: System Reference Document/Discovery and Investigation (section)

====On-the-scene investigation====

The most obvious example of an investigation is where you arrive on the scene where something has happened and try to divine the details. Skills and aspects that allow on the spot observation will help you find clues on the first look. Clues in this kind of investigation will most likely be the description of details that are significant and out of the ordinary. These will usually presented as the details themselves without much context.

=====Advantages in Investigations=====

You can create advantages by doing preparation work. Setting up additional equipment and doing research ahead of time make an excellent basis for rolls and a way to bring in skills that may not have direct investigative uses into play.

Costs for success can include accidentally destroying evidence, otherwise cutting off access to other clues, or angering others involved in the situation. 

Clues may or may not be aspects, but an advantage action could make one more relevant by making it a situation aspect. Reserve the aspect and it will continue to be useful, maybe in subsequent investigations.
