midnight
But you did n't find any sack I took when your bank was robbed -- if it was robbed , '' added the old man significantly . `` Of course , I knew you would have an alibi . Have you got one to explain why you left town so suddenly the night the bank was robbed ? Milton was killed after midnight . Before morning you and your friend Elliot routed out Ackroyd and bought a lot of supplies from him for a hurry-up trip . You slipped around to the corral and hit the trail right into the blizzard . Will you tell me why you were in such a hurry to get away , if it was n't to escape from the town where you had murdered a decent old fellow who never had harmed a soul ? ''
