By the by, the dealer is infuriated with Markheim’s coming from the very beginning. The dealer looks busy and encourages the visitor to cut things short.
Yet Markheim keeps talking to the store seller. He says he doesn’t want the mirror, thinking the gift would insult him in front of his girlfriend. Markheim even offers a friendship with the dealer which definitely meets with an objection. The dealer gets even more furious, asking Markheim to either buy the mirror or leave.
Just when the seller has his emotions heated up, Markheim stabs him from the back. He is now dead. Instead of running away to far places, Markheim goes upstairs. He takes the dealer’s keys, goes into a room wishing he would find abundant amount of money.
