Molly and Sherlock go undercover as a married couple, to bring down Set Carter, a leading drugs lord with a secret society that could be the key to his downfall. The pair, along with John and Mary, are tested physically, morally and emotionally. Will they all realise what it means to be the people they are with the careers they have? Will romance blossom?

Oneshot: Sherlock and Molly find themselves trapped in a storage room. Temptation and close proximity become too much. Rated M for a reason. Best not to read if you're not fond of smutty fiction.
