"The Guide To Mysterious Loch Ness" by Geoff Holder (2007 Tempus)
A rather fine book covering lots of sites in the area around Inverness and Loch Ness, includes folkore, "paranormal" stuff, prehistory, sites of historical interest, very readable and basically a narrative gazetteer.
Well worth looking for if you're getting to know the area around Loch Ness (Drew).
