Which ones do you still need? I can probably remember a few, but not all of them. Here are the ones I remember:
Big Ben: Behind boxes on one of the floors. Sorry, can't remember which.
Newgate Prison: Took me FOREVER to find, but someone finally told me it was behind these grey bricks by a police officer. It is right outside that big tower place.
Reagant's Square (I think that's what it is called): Right by the enterance to Scotland Yard.
Digmoore Station: When you go inside, go by Sherlock Bones. Then turn around to the enterance and you should see him.
I can't remember what area the other ones are in. Please tell me which ones you need and I can tell you. And hurry, because I just beat Marleybone so right now I can still remember them, but I may not for long. :)
Regent's Square cat-Near Scotland building. Digmoore Station cat-Near the elevator to go back to Regent's Square. Hyde Park cat-Near the greenhouse where you get ambushed. Chelsea Court cat-Near the Chelsea Court tower you find Baxter in. Ironworks cat-Go up the stairs behind Pops O' leary, and you will find it. Scotland Yard Roof cat-Look near the entrance to Knight's Court. Newgate Prison cat-Look around where the prison ends. Knight's Court cat-Near Doctor Xavior Xandros's/Jacques the Scratcher's tower. Katzenstein's Lab cat-Look to the right when you enter his Lab. Big Ben-Look around on each floor, it should be in one of the higher floors.
Thank you all very much for this information. I've been having a really hard time finding a few of these while others I just so happen to run into by accident. This is very useful information and I for one appreciate the help
