Who was that masked woman?

That was the question plaguing Perry Mason. No one loves a good mystery more than Mason - but being asked to represent a client who is concealing her identity, not to mention the particulars of her case, has given even the legendary legal eagle a case of ruffled feathers.

Yet the intriguing cloak-and-dagger tactics have Perry hopelessly hooked. As for the silent siren behind the mask, is she heiress Byrl Gailord or penniless Adelle Hastings? Both women have ties to a man named Tidings, a man who may be a protector or predator. A man who could answer a lot of tough questions - if only he hadn’t been murdered.
