Plot

Perry and Della find a baby in his office leading Della to be a mom and Perry trying to find the mother. He finds another man is also trying to sell information about the baby. When he is found dead, the mother looks to be guilty.

Perry Mason and Della Street are shocked when they stop in at the office late one evening and find a baby on Perry's desk. The building cleaning woman, Mrs. Cosgrove, assures them no one was let into the office. While Della takes charge of the baby, Paul Drake starts to trace the child's parents. The only lead he has is a note saying the baby's name is Leander and an old St. Christopher's medal that was left with the baby that has an old electric car engraved on the back. A car dealer tells them the car pictured on the medallion is a rarity with only 6 ever built by its designer, Leander Kerrick. The man is now dead but his widow, Dolly, is still alive. Mrs. Kerrick's cousin and business manager, Jarvis Baker, knows more than he's letting on but she refuses to believe the child might be her grandson. Perry is not the first person to approach her about a possible grandchild since Lester Menke offered to find the child for her for a hefty fee. The child's mother is Ginny Talbot and, when the scheming Menke is murdered, Ginny is arrested and Perry defends her.—garykmcd
