London, Cassell, 1906. First edition, first impression. Hardback. A very good copy. A lost race novel wherein a huge submarine ventures beneath the north pole to find an array of creatures including the eponymous wolf-men. Some rubbing to the boards, and softening to the spine tips. Gift inscription to the front endpaper and a little bit of spotting to the prelims. [10943, Hyraxia Books].
