So I got inspired to write more parentlock, but because it’s me, I went the kidnapping route:

The Case of the Taken Toddler:Sherlock Holmes likes challenging cases. But when it’s his own son that’s been kidnapped, he and John will stop at nothing to get him back.

Teaser below the cut

Hamish and Sherlock were both on the floor in the sitting room, playing with some wooden blocks with the periodic elements on them. John had no idea where Sherlock had found them, but his partner was enjoying explaining the elements to Hamish almost as much as Hamish enjoyed stacking up the blocks and knocking them down.

Sipping his tea, John made a few more notes for the blog. Things had slowed down considerably for them, but he’d never ask Sherlock to give up his work. Besides, with Mrs. Hudson just downstairs, they had a babysitter any time they wanted. And Hamish had taken to calling her Nana, which just made the woman’s heart melt every time.

The little boy had that effect on everyone. John was careful not to spoil him, but he had to keep a close eye on Sherlock. Hamish could charm treats out of the man with just a flash of his little dimples. The boy picked up a block and chucked it hard at his father.

Sherlock caught it and looked at Hamish, knowing John was watching. “What did we say about throwing things?”

“Um,” Hamish smiled up at him.

Sherlock raised an eyebrow. “Hamish.”

Hamish met his eyes a moment, then looked back at the floor. “Don’t.”

“Right. Don’t throw things. You might hurt someone.” Sherlock stood up smoothly and headed for the kitchen. Hamish looked at his Papa.

“Put your blocks away, it’s almost supper,” said John.
