Sherlock Holmes: The Devil's Daughter

Note: Do not skip this sequence because if you do, you will miss out on unlocking this achievement.

Towards the end of the ‘Infamy’ case, you witness Orson Wilde being shoved into a cab at gunpoint. Running out of your apartment, you hail a cab in the street and order the driver to follow the other cab. Your journey takes you to the gates of St. Patrick’s Abbey.

You must first travel through a graveyard that surrounds the abbey while avoiding the lookouts. Use your detective mode () to highlight where the lookouts are walking to sneak around them. If you are seen, a red arrow appears above the lookout’s head as he tries to locate you. Do your best to hide so you are not found.

Once you have found the cab that Orson was in, search it for clues. Then enter the abbey itself through a side passage (as the front door is locked). Again, use your detective mode to avoid the lookouts while making your way to the far end of the abbey.

When you get near the big door at the far end, you will see a bell in the shadows that you must ring in order to distract the lookout guarding the door. As soon as you ring it, climb up a nearby ladder and sneak across the scaffold, drop down and open the door. As the game is loading the next scene, the achievement will unlock.

This achievement starts at [59:00] in the case walkthrough video in “Lock, Stock, and Two Smoking Detectives.”
