Bajoran widow who hired Quark to recover her late husband's strongbox, which held a list of collaborators she was blackmailing.
Vaatrik Pallra is the widow of Vaatrik, a Bajoran murdered on Terok Nor during the occupation. In Necessary Evil, she hires Quark to retrieve a strongbox from her husband's old shop on Deep Space Nine, but a stranger shoots Quark and takes the list of names it contains.
In flashbacks, Odo questions Pallra during his first murder investigation five years earlier. In the present he discovers that the list names Bajorans who collaborated with the Cardassians and that Pallra has been blackmailing them, paying the assassin who tried to silence Quark.
