Journalist Vicky Ward Dives into Ghislaine Maxwell Case in New Doc |

EXPLAIN YOURSELVES

Ghislaine Maxwell seems to be full of secrets -- including what she knows about Jeffrey Epstein and his powerful pals, and one journo is hoping to unlock the mystery once and for all.

The British socialite -- who was tight with Epstein for years before he was charged anew in 2019, and subsequently killed himself -- is about to have her day in court over alleged sex trafficking, among other charges she's facing ... which will be decided at trial later this month.

Of course, many see Maxwell as the key to unlocking the long suspected malfeasance Epstein was conducting with underage girls -- and that goes doubly so for reporter Vicky Ward.

We talked to Vicky on "TMZ Live" about the "Chasing Ghislaine" documentary she's just released on Discovery+, and she tells us a lot of new information is uncovered through her investigation ... one she's been digging into and working on for over a decade now.

Something that's clear to Vicky about Epstein's alleged criminal acts is he clearly had a support system of influential allies spanning the entire globe. Many of those ties to powerful people have already been exposed -- but Vicky wonders how they could NOT have known what Epstein was doing.

She does not suggest any one of these men participated in anything unseemly themselves ... but in her eyes (and, frankly, the eyes of many) there's no reason they should've been as cozy with the guy ... especially knowing his sordid history.

Vicky gets into that and more in the 3-part docuseries ... which is streaming now.
