Possibility of creating organizations ( which the majority of males in both europe and america belonged to at the time ) ?

Though with a few political hitches which may or may not get you shot, though front mainly as 'gentlemen's clubs'. Social clubs & Professional Clubs - with or without illegal bits of drinking. Sort of complimentary to speakeasies?

I'm horrible at explaining my ideas in full but underground and above ground organizations which act as the movers and shakers for things or pure recreation - purely confidential of course. They'd be more than slight political liabilities - and a way to unite more completely all the different classes from policemen to bartenders to mafioso, irish and italian.
