The introduction by Francis Thomson is overly long and meandering. A story from Gaelic mythology is clumsily translated, and the author spends too much print on his own classification scheme for ghosts.

Some of the stories in this book appear to be incompletely edited--In the chapter on "Strange Happenings", the author quotes at length from a friend who encountered a ghostly piper, and it seemed to me as though his story was copied from a letter whose pages were jumbled together in the wrong order. One moment the friend is strolling along the burn, the next moment he is roused from his bed by the sound of a ghostly piper.
Also, many of the stories in "Ghosts Spritis and Spectres of Scotland" have been told elsewhere, most notably in James Robertson's "Scottish Ghost Stories".

Definitely read "Ghosts Spirits and Spectres of Scotland" if you like frightening stories with a Gaelic twist. There are enough ghostly pipers in this book to entertain even the most ardent admirer of Scottish lore.
