Lt. Avery

[fluff]

From the official site:

A second generation police officer, following in her late father’s footsteps. Recently promoted to Lieutenant, she finds the onerous task of giving orders to long-time friend Hayes made even more complicated by the exasperating presence of John Doe. Although she prefers to toe the company line, she can’t deny the results Doe’s special gifts bring to her tougher cases.
