Apache2: How do I restrict access to a directory, but allow access to one file within it?

# No one needs to access this directly
<Directory /var/www/DangerousDirectory/>
   Order Deny,allow
   Deny from all
</Directory>
# But this file is OK:
<Files /var/www/DangerousDirectory/SafeFile.html>
   Order Deny,Allow
   Allow from all
</Files>

And if this directory is password-protected, add Satisfy any too.

There is an answer on StackOverflow that should answer this question, I think there is a missing Order in the nested Files directive?
