Goldy and Marla are excited about the fun nature of their latest catering gig, a by invitation only medieval ball and dinner at Sir Alistair Harrows' home, Hyde Castle, it a fundraiser for Elk Park Prep Academy, the school that Olive attends, she who will be part of a fencing demonstration at the gala. A stickler for authenticity as his home is one big medieval castle without the latest technology such as computers, Internet or cell phones, Sir Alistair dictates to his butler Klaus that all the guests must be dressed in medieval costume, and only invited guests are to be allowed in. Among the guests are many from the Elk Park Police Department, including Tom, Mason and Dave. One uninvited person who is able to make his way in, just before a storm snows them all in, is US Marshal Gerard Trach, Dave's father, who has come to see Tom to question him about his convict father Edmund Schultz as he has escaped from prison, odd in that he would soon be eligible for parole after twenty-five years served for murder. Tom knows nothing about Edmund's whereabouts as he has not spoken to his father since he went to prison, with this news dampening his spirit just before he and Goldy are to go on a big date. Something else that dampens the entire evening is a murder, the victim who was just about to make a self-described earth-shattering announcement. Tom leads the investigation, with Mason and Dave providing official assistance, Gerard somewhat unofficial assistance, and Goldy her inherent sleuthing skills. Even if they don't know the nature of the victim's announcement, they discover that there are many possible suspects as the victim had many enemies among the guests who can't leave even if they wanted to because of the snow. But what Tom probably did not expect is that his father would factor into the proceedings.
