Easy as $#*&

Solution

The first names are from the Mafia module.

The middle initial is an arithmetic operation, for example as seen in Color Math.

The last name is a clue to one of the sounds from the Listening module. The title and flavour text hint to associate the symbols with values ($ = 1, # = 2, * = 3, & = 4).

Applying the arithmetic operation to the Mafia number and the sum of the values of the Listening symbols yields the solution word encoded as A1Z26.
