Advent Drabble 22 - Giftbox (requested by lostmoon71)

“Christmas is a time for surprises,” John told Sherlock, carefully placing the giftbox under the tree.

“No, it’s not. I’m just going to deduce what it is.”

“No,” John commanded, firmly. “You’re not. You’re going to leave it be.”

Sherlock frowned. John purposely went to make a cup of tea and smiled to himself when he heard the small puff of the tiny explosion, followed by Sherlock coughing in the wake of the smoke.

“Shook the box, did you?” John asked, mildly, when Sherlock staggered his way into the kitchen.

Sherlock glared. “Evil.”

“Should have deduced that.”

“Hmph,” Sherlock scowled.
