The Contingency Plan

Nostalgia can do funny things to a person. Make them yearn for the tragedies of the days long gone. Or dream softly of happier things in the face of certain destruction. Locked in a gas chamber with nothing more to look forward to than a traitor's death, Shiho Miyano could think only of the letter folded neatly in her lab coat pocket. The last words of the last of her family.
While fate would see her through that horrid night, she kept the paper as a momento, never suspecting the secrets it contained. For Akemi Miyano was no fool. Knowing not to trust the black organization she stole enough evidence to leverage their freedom, encrypting its location in one final message to her little sister. A contingency plan should the billion yen heist go awry.
Every file on APTX, all the ammunition a detective could ever need, the holy grail is waiting, just beyond the rising sun. Forced to don their old lives, Shiho Miyano and Kudo Shinichi must travel to California and call upon all their wit and cunning to evade the cold eye of a ghost from the past. Her former handler. Codename: Moonshine.
The truth shall prevail.
