Wilson Harris's tenth novel, first published in 1972, is set in Edinburgh but, like much of his subsequent work, bridges continents by its imaginative reach.''Doctor Black Marsden', tramp, shaman, and conjurer, is an ambivalent Merlin-figure representing both the hero's personal (and archetypal) shadow, and the creative, magus-like activity of the author himself.' Michael Gilkes, "Journal of Commonwealth Literature"'… my many visits to Scotland, and books I have read, have given me the sensation of a tone or inner vibrancy that may be due to the languages (English, Scottish, Gaelic) that are present in the subconscious imagination of sensitive Scots… [These] make for the cross-culturality (not mono-cultural) that came into play in Black Marsden.' Wilson Harris, 2008
