"The Devil Box" is a D&D adventure suitable for four 2nd-level PCs, although it can be modified for parties of 1st or 4th-5th levels as noted int the "Scaling the Adventure" sidebar. Characters completing the adventure are likely to advance to 3rd level. Much of the action takes place in a small town during a festival; this town can easily be dropped into an existing campaign.

Uploader's note: A hilariously creepy adventure involving a circus (freakshow), with in style illustrations! (Grid maps included, but not separate maps.)
