Which text is valuable for gaining context about a historical event but is unreliable as evidence?

A Historical Novel is valuable for gaining context about a historical event but is unreliable as evidence. Historical Novel can give us an idea about how the events can be linked and some material is useful for reference.

But it is purely fictional. Therefore, it is not possible to use it as evidence for the events occurred. Hence, a Historical Novel can be referred to for gaining information or some context but is not reliable.
