Read it through once

Wilson regarded the case of the twins as desperate--in fact, about hopeless. For he argued that if a confederate was not found, an enlightened Missouri jury would hang them, sure; if a confederate was found, that would not improve the matter, but simply furnish one more person for the sheriff to hang. Nothing could save the twins but the discovery of a person who did the murder on his sole personal account--an undertaking which had all the aspect of the impossible. Still, the person who made the finger-prints must be sought. The twins might have no case with him, but they certainly would have none without him.
