On Sunday's episode of Timeless, the team travels back to 1919 New York City when suffragette Alice Paul is framed for murder and they partner up with legendary crime solver Grace Humiston (guest star Sarah Sokolovic), also known as Mrs. Sherlock Holmes, for a much-needed assist after their attempts at visiting the imprisoned Alice come up empty.
In ET's exclusive sneak peek, former lovebirds Lucy (Abigail Spencer) and Wyatt (Matt Lanter) seek out Grace, a "brilliant" lawyer and investigator the NYPD used to solve crimes they couldn't crack themselves. But it's not their mission that catches Grace's attention when the pair first step into her office.
"Mrs. Humiston?" Lucy breaks the ice, causing Grace to look up from her notebook.
"Sorry, I don't take romantic disputes," Grace immediately says, catching Lucy and Wyatt completely off guard. "If you want my advice, you have have better things to do than to waste your time and keen intellect on a married man, even if he is a soldier and a war hero."
Lucy's face goes ghost-white when Mrs. Sherlock Holmes accurately calls out her and Wyatt's... awkward situation. There's no doubt Grace has earned her nickname, as she easily runs down to a T how she deduced that Wyatt was a soldier. But she wasn't done.
"You're wearing a wedding ring. She's not. She's trying to keep her distance from you. You're trying to get closer... and I'm betting he didn't tell you about the wife, either," Grace observes, as Lucy's mouth goes agape. "But that one's just a guess." Ding ding ding!
"You know, it's a little bit more complicated than that," Wyatt says, getting defensive. Is it though? Watch the exclusive sneak peek above to watch the rest of the scene.
