Lacie sees a faded blue ink mark on David and Virginia's headstone.

"How concerned should we be that Virginia's name is on a tombstone out here?"

"It's probably just prepared for her for when she dies."

Reassured that there are no creepy undead shenanigans here, merely reasonable practices of paying for expensive and inevitable things over time instead of all at once, Lacie points out the blue ink marks to Carrie.

Carrie checks to see if the distance between the marks on the graves matches up with any of the ink marks on the twine

Zoe finds Zachariah and Millicent on a gravestone! And there's an ink mark!

And a John and Mary together over here!

Carrie carefully checks to see if the marks on the twine match up with the graves. Starting with the second mark, she extends it from Grant to John & Mary to Zachariah & Millicent.

"Five and one may or may not have names but if someone holds down the twine on Zachary and Millicent, then someone else can find the grave that's the appropriate distance away?"

With Mordred's help, she carefully arranges the square and discovers that point one was David and Virginia's grave.

As Zoe stands on David's grave, she glances at the photo and notices that the view is the same-- Mr. Henslowe was standing on his father's grave as he took the photo.

Carrie notices that there's a knot on each of the four sides of the square.

"I wonder why he didn't note it down. Maybe it felt obvious? Or maybe he didn't want... it feels like he might have been hiding it but I'm not sure whether from his mother or from something else."

"Well, he said he left the way to find his journal with Hickering... and the photo was in Hickering's book..."

Carrie wonders if the knots line up particularly with anything, since they're not in the centers. She looks at them carefully but they don't seem to correspond to anything.

In the hopes that they won't have to dig up a grave Zoe checks inside the vase for journals. No such luck.

There is one knot on each side, so it forms a smaller square...

Does wherever the lines from knots opposite each other would intersect lie over anything in particular?

Carrie calculates the spot and finds a spot where, examining it closely, she sees that the grass is slightly less overgrown... like someone dug it up.

"Soooo anybody bring a shovel?"

"I have the shovel. I really don't wanna dig in a graveyard, though."

"Do we want to do this now, or do we want to dig up a graveyard by daylight rather than flashlight?"

"No, you wanna dig up someone else's graveyard at night, so they don't stop you in the middle of it and call the cops."

"It's not actually over a grave, so it's not graverobbing?"

"Aight! Let's dig up a graveyard."

"On that note I am going to go back into the house and distract Carruthers by asking if there's any dinner to be had."

After the investigators spend fifteen minutes arguing about who's digging, digging takes the better part of an hour. Anemone determinedly digs for five minutes, realizes she is sickly, and hands it over to Mordred and Lacie to finish the job.

The night is hot and wet, like the inside of a mouth. A dead newspaper slips between the tombstones on an all-but-imperceptible gust of warm wind. The sound of it brushing against the stone is like a whisper in a foreign tongue.

Carrie grabs for the newspaper. Either it was left here and is significant or is trash and should maybe be thrown out somewhere. 

It is trash. She decides to hang onto it to throw out properly elsewhere unless it is particularly gross in some way.

Carrie, throwing out one newspaper will not help the state of decay of this estate. You are a sweetheart.

Fun fact: literally everything about "The night is hot and wet, like the inside of a mouth" is gross in some way. Why is the South.
