Question

How did the intruder prepare himself to take up the identity of gerrard?

Answer 1

He had heard about gerrard that he doesn't meet trades people or any other common people so he went to his cottage with a revolver and just got over him...he thought that after taking on gerrards identity he would be free to go places and do nothing also if he would be caught by chance he would not be hanged twice for two murders..
