Mumps to Murder--Three Gees Novels

In Gees’ First Case, Gees, a budding Private Detective—described by the author as pleasantly ugly, tall, with very large hands and feet, though not at all ungainly—finds himself involved in a conspiracy to overthrow the British government.
Grey Shapes gets Gees into more mysterious situations as some supernatural (Gees insists it is “subnatural”) force is killing sheep and draining their blood in the north of England.
In The Ninth Life, Gees falls into further supernatural trouble. His friend Tony is enchanted by a 5,000-year-old Egyptian priestess—and children keep turning up dead, mangled by giant cats.
