#20 The Silent Twins by Marjorie Wallace
I remembed watching an Unsolved Mysterious episode about these girls. They grew up never talking to a single person and everyone assumed they were mute... and just slightly off. When they are caught redhanded attempting to start a building on fire, police realize that they had just captured the arsonist that had been plaguing the town for weeks.
Over all... I enjoyed the book as it was able to get inside the twins heads. Not an easy job as they are largely uncommunicative. But with the help of detailed dairies they wrote at home and in prison, psychiatrists were able to determine exactly what made the girls tick.
2 out of 5 stars. I was displeased by Marjorie Wallace's writing style. The book would have been much better written by someone else.
