I ran Rats in the Walls for my group and it was a huge success! I normally cringe at the tired old trope of 1st level characters clearing rats out of a cellar but this was a pleasant surprise. The straighforward plot and succinct but evocative exposition allowed me to run this adventure with minimal prep; the adventure was a lot of fun for all involved.

Out of 14 pages, 10 and a quarter are the content.

An Inn/tavern keeper requestng help from the players, as he has a serious rat problem. Sounds simple enough; not really. Quite a good scenario for beginning players. It appears as a fairly standard 'dungeon crawl', with rats as the main antagonist, and a suprise one at the end.

There are also some secret doors, and the loot (which should keep the players well equipped for a while).

There's also an ending note about a possible were creature - interesting.

The only thing I found that stopped this scenario from getting a 5/5, is on page 7. It shows a map of the dock where the inn/tavern is, and 4 very small floor maps all on one page. I had to zoom the page to 150% to see the maps. These could have been put on a separate page or two to make them bigger, giving a much better view of them.
