Looking for a fic

[crazy-larmo.livejournal.com]

I swear i bookmarked this but apparently i didn't

It's a buckey fic where hes on a mission to kill Howard stark but he is instead captured and they manage to recovers his memories temporarily and he becomes a double agent and is activated by the words 'come in from the cold' i think. Later on he bumps into Loki who as a troll restores his memories completely.
