Irma issued a negotiable promissory note to her Certified Public Accountant (CPA) in return for the CPA's promise to prepare and file her business taxes.The CPA never prepared for filed Irma's business taxes, but quickly negotiated the note to Ann, a holder in due course.

Meanwhile, Ann and Mary were involved in business negotiations and Ann offered to purchase business equipment from Mary. Ann offered, as part payment for the business equipment, the note issued by Irma.

eventually sued Irma to collect.What is the probable outcome?
