What are the names of books where Nancy Drew is chloroformed?

Answer 1

Nancy is not chloroformed too much in the original series, she is usually knocked out by a blow to her head or Nancy faints for a variety of reasons. Nancy does get chloroformed, however, in Nancys Mysterious Letter when she is grabbed from behind by a strange girl who hold a chloroform soaked pad over Nancys nose and mouth and Nancy quickly blacks out. In the Nancy Drew files chloroform becomes the favourite way for the bad guys or girls to knock Nancy out
