The case involves a woman named Mildred Faulkner who owns and operates three successful flower shops. Her partner in the stores is her sister, Carlotta, but Carlotta has been ill and out of action for several months, leaving Mildred to run things by herself. Mildred and Carlotta own all the stock in the corporation, save for a few shares that they gave to an early employee. Now, one of their competitors has managed to get his hands on those shares and intends to use them to chisel his way into their business.

Obviously concerned, Mildred goes to see Carlotta. Her sister's affairs are now being handled by her husband, Bob, who Mildred never liked. Bob is an irresponsible lout who plays the horses and who may be playing around on his sick wife, but Carlotta is blinded by love and can't see through Bob the way Mildred does.

Mildred tells Bob that she want's Carlotta's stock certificates so that she can take all the certificates to a lawyer and attempt to deal with the threat to her company. But Bob weasels around and Mildred suddenly realizes that he may have turned Carlotta's certificates over to a gambler as collateral for a debt. Now thoroughly panicked, Mildred contacts Perry Mason and gets him on the case. But before you can say, "Della Street," somebody's dead and Mildred is in even more trouble than she could have possibly imagined. We can only hope that Mason will be able to save the day.
