Midwest Book Review says this about Ghost Letter: “A deftly crafted mystery suspense novel that reveals author Helen Currie Foster to be a true master of the genre, Ghost Letter is the third in a series of Alice MacDonald Greer stories. Impressively well written from beginning to end, Ghost Letter is an exceptionally compelling and thoroughly absorbing read that is especially recommended for the personal reading lists of dedicated mystery buffs and would prove to be an enduringly popular addition to any community library Mystery/Suspense collections. . . Also very highly recommended are the first two novels of this outstanding mystery series: Ghost Cave…; Ghost Dog.
