William Baker

In the novel 4.50 from Paddington, William Baker is a ticket collector at Brackhampton station. On the day of the murder, he clipped the ticket of a man whom he recognised by sight as "one of Miss Crackenthorpe's brothers" just before the departure of the eleven-fifty-five train for Paddington. It is not confirmed which brother it was, but the police believe it to be Alfred Crackenthorpe.
