Suzy gets Joe to fix her computer while she is on vacation. Because she does not know how much the job will cost, she gives Joe a signed blank check with Joe as the payee. Joe, of course, is supposed to fill in the correct amount and cash the check at Suzy's bank. The job costs $200, but Joe fills out the check for $10,000 and then negotiates it to Harry. Harry takes the check in good faith, for value, and without notice of the false addition. Assuming that Suzy's bank does not pay to Harry and Harry pursues her on her secondary liability, does Suzy have an alteration defense against Harry?
