Sherlock Holmes Chapter One

This achievement is missable, and is earned for completeing the Cordona Story 'The Tale of the Empty House'. The achievement only requires completion of this side case, but is still missable, as if you get past the point of no return before completing it you cannot go back unless you re-load an older save.

To get this Cordona Story completed, you need to have unlocked the 'Sacrifical Lamb' main story case, which starts once you've completed all Fragmented memories in the manor. You can start this side story before this, but some of the items you need to purchase are locked until you have access to the entire manor. To explain in layman's terms, unlock the below story related achievement, then just play on for 10-15 more minutes until the 'Sacrificial Lamb' main story case pops on your screen, then save.



This is a straightforward Cordona story, which requires you to buy 22 items worth 640 money. You should have ample money from your main cases, so long as you aren't spending your money on pointless outfits.

Once you have done this, you should get 5 case book clues stating that each area of the house is complete (front yard, main lobby, Sherlock's room, Violet's room, Mycroft's curiosity room). If you aren't getting these clues, you need to buy more items (don't forget the progression required, detailed above).

Once you have these clues, return to the manor, and pin each prompt pertinent to the room/area you're in, and investigate all clues. Rinse and repeat for all 5 rooms/areas. You'll need to use focus, which is the RB button. Once you've done this, the story will end and the achievement will unlock simultaneously.

If you need money, complete some of the other Cordona stories/side cases first, and/or complete Bandit Lairs.
