Mary Louise in the Country

The Bluebird Books is a series of novels popular with teenage girls in the 1910s and 1920s. The series was begun by L. Frank Baum using his Edith Van Dyne pseudonym, then continued by at least three others, all using the same pseudonym. Baum wrote the first four books in the series, possibly with help from his son, Harry Neal Baum, on the third. The books are concerned with adolescent girl detectives- a concept Baum had experimented with earlier, in The Daring Twins (1911) and Phoebe Daring (1912). The Bluebird series began with Mary Louise, originally written as a tribute to Baum's favorite sister, Mary Louise Baum Brewster. Baum's publisher, Reilly & Britton, rejected that manuscript, apparently judging the heroine too independent. Baum wrote a new Version of the book; the original manuscript is lost. The title character is Mary Louise Burrows.In this volume, Mary Louise and Gran'pa Jim take a house for the summer in a quiet place called Cragg's Crossing. There, they meet with any number of peculiar people - and one very peculiar mystery!! (Summary from Wikipedia and Sibella Denton)
