The certified public accounting partnership of James, Guinn, and Head prepared a certified audit report of four corporations, known as the Paschal Enterprises, with knowledge that their report would be used to induce Shatterproof Glass Corp. to lend money to those corporations. The report showed the corporations to be solvent when in fact they were insolvent. Shatterproof relied on the audit report, loaned approximately $500,000 to the four corporations, and lost almost all of it because the liabilities of the companies were in excess of their assets. Shatterproof claimed that James and other accountants had been negligent in preparing the report and sued them to recover the loss on the loan. The accountants raised the defense that they had been retained not by Shatterproof but by Paschal. Was this defense valid? [Shatterproof Glass Corp. v. James, 466 S.W.2d 873 (Tex. App.)]
