I don't remember much it's about one of Kogoro client a lady looking for her friend location her friend sent a clue, and on another case a gun was stolen and the lady took it to kill her friend and his fiancee the friend is her ex and she wanted to kill him because of sadness(?) And before she kills him Conan talks to her in the phone and she stopped and congratulated her
I racked my brain, and felt it seemed familiar, yet when I search it, everything is in fact wrong. Any other hint?
Hm the lady gave a clue about the map the map was colored each color represent something and i think one of the clue was near a bridge?
Crossroad in the Ancient Capital? or Distinguished Family's Consecutive Accidental Death Case? Maybe both of them are wrong, well. I'm sorry I can't help much.
