Then Mjolnir realized he was hearing a flute. Faint at first, but getting stronger and louder with each passing minute. He peered through the screen door toward Aunt Cathy and saw Cassie sitting on the floor beside her, hands raised, the flute to her lips. She finished the air she was piping then laid the flute down, reached out her hand and gently stroked Aunt Cathy's forehead. Cathy reached up and took Cassie's hand in her own. Mjolnir relaxed and started purring. He must be getting senile to forget that Cassie didn't need a spell from him to come to Cathy. He'd just go on in now and join them--or he would if he could get inside the damned house!
    He yeowed again, loudly. Cassie and Aunt Cathy both turned to look at him. "Sorry, my dear old familiar," said Cassie. "I would love for you to join us while I summon Louie to come and help, but I can not possibly do something so corporeal as unlatching the screen. You will have to find your own way in. And while you are at it, find a way to let this poor dog out before he bursts his bladder." Duke was continuing to pace back and forth between the door and the women, whining and panting.
    Mjolnir sat glaring at the dog, wondering what it would take to get the old dog to bust through the screen door. He rose again, peered one last time into the kitchen at the women it was his destiny to protect, then turned abruptly and disappeared from view. When he was gone, Cassie raised the flute to her mouth once more.
