Skulduggerous

You feel slimy and skulduggerous. You feel nervous that they'll return unexpectedly and catch you at something nefarious, even if the someone is in jail.

A number of skulduggerous means were used, including hoarding its rival's banknotes.

In their hopes of overthrowing an unjust society, many of these groups held to romantic models of secret conspiratorial organisations. This skulduggerous, dashing lineage was reflected in the elusive, allusive poetry of some of their names: the Society of the Families; the Society of Seasons; the Leage of the Proscribed.
