This classic novel of the weird supernatural, first published in 1908, was an important influence on H. P. Lovecraft. In the ruins of an ancient stone house in Ireland is found the diary of an elderly man who lived alone with his sister and their pets, and who longed for his lost love. The diary tells of how the man explores a cyclopean cavern beneath the house and fights off swarms of white pig-like monsters pouring up from below. Then, in a visionary sequence, he breaks through to an alternate space-time dimension and sees a doppelganger of his house on a vast desolate plain. The prose is hokey at times, but the strange mood evoked by the other-dimensional setting is powerful indeed.
