The Safekeeper's adventure continues... "Welcome to the Greenmont Grith Business Center. Watch out for crossing aliens." Safekeeper Macy Steward is hosting a perimeter guard competition. An intergalactic perimeter guard competition, in preparation for the grand re-opening of Greenmont Grith as a Business Center. She also happens to be babysitting the Exchange Guides’ newborn, as well as dealing with the suspicious visitors who’ve arrived unexpectedly in the middle of the night. Most alarming of all, Macy has discovered a dead body. Inside her Center. She has only three days to solve the mysterious murder before the Orbit Council decides that Macy is such a terrible Safekeeper, Greenmont Grith’s doors should be closed for good. At least the Center has been put on lockdown until the perimeter guard competition is over. Nobody, including Macy, is able to leave the Center grounds, a binding rule put in place by the Orbit Council. But, wait, doesn’t that mean the murderer is trapped along with all the other guests? Oh, yes, indeed. That’s exactly what it means.
