"Live fast, die young, bad girls do it well," he replied with a laugh. To himself, he recalled his actual motto - he who seeks to deceive will always find someone who will allow himself to be deceived.

age: 42

sexuality: heterosexual

gender: cis man

pronouns: he/him

occupation: inventory person at partner in crime (former jewel thief)

traits: clever, charming, adrenaline-hungry, morally ambiguous, and mendacious

extra: Once upon a time, John Harrison had a different name and different life. He’d begun his life in France and managed to score a scholarship to a top private school. However, affording school was one thing, and John started up a life of petty thievery to support himself and his parents. He’d gradually escalate for years and years, pulling more valuable and ostentatious grabs, until he and his main partner in crime managed a heist from one of the biggest banks in France. They both immediately fled France, riches in hand and assumed new identities in Canada. Part of John’s new identity? Getting married as soon as possible. He tries not to feel bad, wooing Elizabeth into a quick marriage just to have a cover in Canada, but he tries to treat her well, slowly spending his bank money so as not to tip her or anyone else off.
