Murder between the lines

the long version

When Kitty's latest assignment for the New York Sentinel Ladies' Page takes her to Westfield Hall, she expects to find an orderly establishment teaching French and dancing-but there's more going on at the school than initially meets the eye. Tragedy strikes when a student named Elspeth is found frozen to death in Central Park. The doctors proclaim that the girl's sleepwalking was the cause, but Kitty isn't so sure. Determined to uncover the truth, Kitty must investigate a more chilling scenario-a murder that may involve Elspeth's scientist father and a new invention by a man named Thomas Edison.
