Office Christmas Sweater Murder Mystery

The Romanage International company office, just south of London, is throwing its annual “Ugly Sweater” lunch for employees, clients and vendors. It’s going about the same as any daytime office party with no alcohol—dull and quiet, with everyone on their best behaviour.

Then a scream rings out—the company president, Mike Romanage himself, has been found dead in the copy room. His head was bashed in as he bent over the glass of the old-fashioned copier. Unfortunately, the body collapsed onto the “Print” button, so hundreds of copies of his astonished face are flying around the room.

The guests, mingling uneasily among the cubicles, are abuzz with questions. What was Mike Romanage copying? Who’s in charge here? When can we go home? And most importantly—whodunit? Could it have been YOU?
