Jane bought a string of pearls from Grantham Jewelers. Jane wrote a check for $1,760 to pay for the pearls. When Jane had the pearls appraised for insurance purposes, she learned from the appraiser that the pearls were fake. Jane stopped payment on the check. However, Grantham had transferred the check to Jim Holub, who had then transferred the check back to Grantham. Is Grantham an HDC?
