"I've located the skeletal remains of Gratian Caerellius. In his satchel, I've discovered an old journal. In order to return it to Crescius, I'll have to discover a way to escape Bloodskal Barrow."
The journal is actually in his (skeletal) remains, not in the satchel next to him. Assuming you think this should be corrected, it would probably be easier to change the text than relocate the journal.
