"A murder investigation," Powell smiled, "explores three facets of a crime. First, the motive. Second, the method. Third, the opportunity. Our Lab people are taking care of the second two. The first we can discover in our game. And if we do, we’ll be able to crack the second two problems that have Lab stumped now. Did you know that they can’t figure out what killed D’Courtney? Did you know that D’Courtney’s daughter has disappeared? She left the house while you were playing ‘Sardine.’ Did you know that D’Courtney’s guards were mysteriously short-circuited? Yes, indeed. Somebody robbed them of a full hour in time. We’d all like to know just how."
