Stuck in the Bank

[mandalman]

I've got into the office as Joanna and searched everything and I know from watching Youtube walkthroughs that i'm meant to switch to poirot by pressing Q (i think it also appears on the mind map as an option). I don'r get the prompt to press Q and pressing Q does nothing so I cannot switch. I've looked all through ther alic in Wonderland book, opened the twoer of Babel to get the key, opened the drawer, photographed the picture in the frame, tried to access the computer. I canot think of anything i haven't done. Help!!!!

I had to go back and forth between the computer, the mind map and stuff in the room. I was also stuck at one point because an item on the computer looked like it was complete but I had to click through it again. Sorry - it's been awhile since I played - but I do remember being frustrated.

When the character is free to roam (i.e. not looking at a clue or reading a text), you should see at bottom left of the screen an icon with the two characters in black and white separated by a "slash" (like on a playing card).

You then press "Q" , which in turn brings up a "Call Poirot" dialog box at the bottom of the screen (or alternatively "Call Mrs Locke").

And indeed, you have to switch back and forth between the two characters a number of times, as they help each other in their search (one discovers clues/codes that the other can use on his/her side, etc.).

My response is a bit late, but maybe it helps you or someone else:

The ability to switch between Locke and Poirot should be unlocked after glancing at everything in the office.

The combination for the Tower of Babel is found in Wadi's apartment. You're not supposed to open it before switching to Poirot once. If you've somehow guessed or brute-forced the combination you might have skipped ahead and soft-locked the game. In that case restarting the chapter might help.
