This is a great short Sword and Sorcery type adventure, that can easily be run in a session. The adventure, though somewhat linear allows the players freedom to try and solve the mystery at hand and of course save the damsel.
There is a bit of problem solving, and a good chase scene that gives the players more to do than just hack and slash their way to the end. The antagonist is thought out and has decent motivations for what he is doing.
The only drawback, is there are a few places where there is an assumption that the players will do the right thing to move the adventure forward. Some might find this a bit railroady, but a good GM should be able to give the PCs a bit of freedom and keep them still on track.
Like all the B&B stuff I have read, this can easily be ported over to other game systems or fantasy setitngs with little effort, making it quiet versatile.
