Meghan Markle's father is familiarizing himself with British history through picture books.

The "Suits" actress' dad seems to be doing his assignment ahead of the royal wedding. Thomas Markle was spotted checking out a British picture book while sitting inside a Starbucks in the town of Rosario Beach in Mexico's Baja California peninsula.

On Wednesday, Dana Schwartz of Entertainment Weekly shared a snap of Thomas checking a book titled "Images of Britain: A Pictorial Journey Through History" on Twitter. "Literally nothing is more pure than Meghan Markle's dad doing some reading to learn more about England," she wrote in the caption.

According to E! News, the book was published in 1990 and has a section about Windsor Castle. This includes St. George's Chapel where Prince Harry and Markle will be tying the knot on May 19.

Prince Harry and Thomas have not yet been seen together. However, it is believed that the two gentlemen share a good relationship. Markle's husband-to-be has reportedly forged a close relationship with his future father-in-law.

"Talk that Harry had upset Tom with comments about their family aren't true," said Lori Davis, Thomas' friend. "He thinks Harry's a great guy – he couldn't have wished for a better son-in-law."

"Tom will call sometimes so I know how he's doing. He's happy his daughter is with Prince Harry and he's glad she's found love. He never expected this. He was expecting a quiet retirement in Mexico," another source named Allison Leber said.

In addition, when Thomas spoke with The Sun about Prince Harry, he has nothing but praise for his future son-in-law.

"I think it's wonderful, I'm very delighted. I think they're (a) very good match, I'm very happy for them, Meghan and Harry," the retired lighting director said. "I love my daughter very much — Harry's a gentleman."

Thomas is expected to give Markle away on her wedding day. His other daughter, Samantha Grant, also claimed that he will give a speech at the reception.
