Clearly an underrated book. The back cover of my book has a quote from Kingsly Amis comparing it to Heart of Darkness, which is apropos. There is not the sense of journey of Heart off Darkness, but there is a sense of sweltering steamy lethargy throughout the book. The book delves into the primitive subconscious and there is a sense of the primeval. The figure of Strangman becomes a kind of lurking evil and there is a continual atmosphere of tropical devolution.
Really very good at setting a tone and a feeling. I read this right after the Martian Chronicles which is not a wholly dissimilar book. This book is better than the Martian Chronicles in every way. In many ways more influenced by colonial literature and literature of the fantastic rather than Science Fiction.
Very good work. Deserves to be much better known than it is.
