What a delightful book. The growth of the friendship between Marge and Enid made this an enjoyable read. Margery Benson transforms from a large woman who teaches school in England, puts her own interests on hold and counts on others to take the lead - into an independent entymologist living in New Caledonia. Enid is hired as Margery’s assistant. Enid is a whirlwind of enthusiasm and innocence - sort of.  
Never understood why Mundic was included in the story. His presence as the potential stalker/foil just never materialized. He was pitiable - not menacing.
