Read it through once

When Wilson reached the house of mourning and had gathered such details as Mrs. Pratt and the rest of the crowd could tell him, he took command as mayor, and gave orders that nothing should be touched, but everything left as it was until Justice Robinson should arrive and take the proper measures as coroner. He cleared everybody out of the room but the twins and himself. The sheriff soon arrived and took the twins away to jail. Wilson told them to keep heart, and promised to do his best in their defense when the case should come to trial. Justice Robinson came presently, and with him Constable Blake. They examined the room thoroughly. They found the knife and the sheath. Wilson noticed that there were finger-prints on the knife-handle. That pleased him, for the twins had required the earliest comers to make a scrutiny of their hands and clothes, and neither these people nor Wilson himself had found any blood-stains upon them. Could there be a possibility that the twins had spoken the truth when they said they found the man dead when they ran into the house in answer to the cry for help? He thought of that mysterious girl at once. But this was not the sort of work for a girl to be engaged in. No matter; Tom Driscoll's room must be examined.
