AN: For as many Sherlock fics I've written, I'm a little disappointed in myself for how little Sherlock is actually featured in them. Naturally, I had to do something about it and I thought of what he would do when it came to my favourite couple in the show. This was the result. Enjoy!

The first word of advice was given the day before her birthday.

Greg's original plan was to give Molly a leather-bound copy of Jane Eyre because he knew that it was her favourite book. He'd seen her reading her old paperback copy several times before and he'd always liked how her eyes would light up whenever she would analyze Jane's character, her relationship with her eccentric employer or her foil with his mad wife.

He was telling John about his plan to buy the copy after work, but he had almost forgotten that Sherlock was in the room studying what appeared to be an orange pip; one of five, in fact.

"Oh, god no," Sherlock said. "You don't want to do that."

"Shut up, Sherlock," John said. His tone was as casual as a simple hello.

"Why don't I?" Greg asked. "It's her favourite book."

"Exactly, so she already has it. She's either got several copies of it at home already or she's emotionally attached to the old paperback she's always reading from because of some sort of sentimental value, though the latter is more likely."

Greg thought for a moment and so did John, as Sherlock returned to his studies as if no conversation had taken place. Molly had spoken fondly of the time she had bought the copy at a weekend trip to Howarth with her grandmother. The consulting dickhead had a very good point, though neither Greg nor John were willing to say so out loud.

"So what would you suggest?" John asked. "Since you're such an expert on the subject of women with a particular obsession with the Brontë sisters."

"Give her something related to the book."

Greg rolled his eyes. "Like what?"

"Pearls."

Greg paused. His brow furrowed. "I don't follow."

It was now Sherlock's turn to roll his eyes as he lifted his gaze from the microscope. "Honestly, Gael…"

"Greg!"

"…for someone who fawns over the woman as often as you do, it amazes me that you haven't even made an effort to read her favourite book, let alone ask her to dinner. If you had, you'd remember that Rochester gives Jane a pearl necklace as an engagement present. Though I'd hardly recommend proposing as quickly as he did and while I dearly hope you haven't driven your ex-wife mad and locked up her in an attic somewhere, the significance of a pearl necklace will have her on her knees. It wouldn't kill you to read the book either."

Sherlock returns to his studies and leaves Greg unable to argue.

"You probably won't be getting it from Marks and Spencer's, then," John added. "And maybe it's best not to mention Sherlock's advice."

Greg nodded in agreement and left before Sherlock could suggest anything else, but as he left he heard something about a vintage shop in Soho. The idea of Sherlock giving him any kind of advice, particularly regarding women, was a little more than unsettling.

He managed to find a pearl necklace in Soho for fifty pounds as well as a copy of Jane Eyre for five on the way home. After boxing and wrapping the necklace he read the book to sleep.

The next day, Greg had visited Molly at the lab and left the gift on her desk for her to find. When he saw Molly at the pub later that day, she was wearing the necklace with pride.

"Thank you, Greg. It's beautiful."

She then did something she had never done before and kissed him on the cheek.
