DC Marcus Hale, Economic Crime Unit, Limehouse
Apartment 12B, Pinnacle Tower, Canary Wharf, London E14
Adam Clarke, 36, tech entrepreneur (theft victim, reporting party)
Adam Clarke reports that a USB hardware wallet holding approximately £1,000,000 in Bitcoin, along with the steel capsule storing its recovery phrase, was taken from a locked drawer in his study. There is no sign of forced entry to the flat. The drawer's lock shows fresh pick marks. Six people sat down to dinner at the flat the previous evening: Mr Clarke, his wife and four guests. A neighbour called at the door during the meal. Mr Clarke is not excluded from the investigation.
Four questions, in order. What do the lock records and the scene examination establish? Who could have reached the study during the evening? Where did the missing coins come to rest, and whose records connect to that account? What do motive, means and the remaining loose ends add up to? Each stage is sealed: prove your reasoning to unlock the next.
