The answer is:
Misplaced modifier: in red ink
Word it should follow: marked
The revised version of the sentence is the following:
He had carefully marked in red ink the places we were to watch for on the map.
Misplaced of dangling modifiers are words or phrases that are wrongly located and cause confusion, ambiguity or nonsense. In the original sentence, the misplaced modifier "in red ink" created complexity and disorientation. As a consequence, it should follow the verb and precede the direct object it modifies.
