The lodger occupied two rooms at the vicarage, which were in an angle by themselves, the one above the other. Below was a large sitting-room; above, his bedroom. They looked out upon a croquet lawn which came up to the windows. We had arrived before the doctor or the police, so that everything was absolutely undisturbed. Let me describe exactly the scene as we saw it upon that misty March morning. It has left an impression which can never be effaced from my mind.
