Valhalla's inheritance

Your late grandfather Quentin was a quiet, eccentric old man—or so you thought. When he leaves you his historic British estate in his will, you expect dusty books and drafty hallways. Instead, you inherit "Valhalla," a cutting-edge smart-home system with a dry British wit and a sharp sense of humor. Turns out, Granddad was "Q," the legendary gadget master of MI6, and your new home is a fortified compound packed with hidden labs, weaponized appliances, and classified secrets. Can you survive the house's lethal defense grids and earn the respect of its sly digital caretaker, or will your first week as heir be your last?
