There are a few reasons why you might not see posts on this friends page:

• Agent Francis Brown might not have any friends defined. If you are Agent Francis Brown, you can edit your LiveJournal friends so they show up here.
• Agent Francis Brown might have friends defined, but all of their friend's posts might be over two weeks old (according to the times on our servers), and thus wouldn't be displayed here.
• Agent Francis Brown might have friends defined that post only protected entries that you can't view, because they haven't defined you as a friend in return.
