Set against the religious struggles of seventeenth-century Scotland, with Montrose for the king against a convenanted kirk, John Buchan's Witch Wood is a gripping atmospheric tale in the spirit of Stevenson and Neil Munro. As a moderate Presbyterian minister, young David Sempill disputes with the extremists of his faith. All around, the defeated remnants of Montrose's men are being harried and slaughtered by the faithful, and Sempill's plea for compassion, like his love for the beautiful Katrine Yester, is out of joint with the times. There are still older conflicts to be faced however, symbolised by the presence of the Melanudrigill Wood, a last remnant of the ancient Caledonian forest. Here there is black magic to be uncovered, but also the more positive pre-Christian intimations of nature worship. In such setting, and faced with the onset of the plague, David Sempill's struggle and eventual disappearance take on a strange and timeless aspect in what was John Buchan's own favourite among his many novels.
