I've picked out Margaret Cameron for you.
We can call you Maggie and it won't be a slip-up--see?
If any of the coppers who know you should tumble on to you, just tell 'em you dropped your own name so's to get clear of your old life.

They can't do anything to you.

And tell 'em you inherited a little coin; that's why you're living so swell.

They can't do anything about that either.
