SF Reader review Jack Primus gave The Angel of Highgate a solid 4 1/2 star review. His only reservations were the lack of solid supernatural underpinnings to the novel. It is an observation I soundly agree with, for I wrote the novel to be open-ended (especially the ending) so that a reader could decided for his or her self whether the supernatural elements were real or imagined by the protagonist, the louche Lord Geoffrey Thraxton.
