What a fun and entertaining story. Capri, the owner of a San Francisco tour company, was the perfect amateur sleuth who was determined to find the copycat killer of her mother- in- law and her mother-in-law’s friend and to prove her grandfather innocent of the original murders years ago that had been dubbed the “overkill Bill” murders. The history of San Francisco and the description of different locales that were featured in ‘noir’ movies like Vertigo and where serial murders took place were an added plus.
