The Lethal Weapon (Detective Conan Fanfiction)

FBI Agent Akai Shuuichi is haunted by two women: a brilliant detective who mysteriously walked out of his life, and the woman he was forced to mourn at the hands of the Black Organization. Their stories are a source of lingering pain, a past he can't seem to escape.
Maria Ashenbert, a woman of warmth and kindness, lives a life of calculated deception as the adopted sister of Kudo Shinichi. She's a master of disguise, her every move a step toward a truth that lurks just beneath the surface. To protect her family and preserve the lives of those caught in her path, she has built a life of lies, a cold facade to hide an aching past.
Their lives are a tangled dance of past and present, a lethal game where love is the most dangerous risk of all. As Akai gets closer to the truth, he'll have to solve a mystery far more intricate than he could ever imagine.
Will the truth finally unite them, or will it be the very thing that tears them apart?
