When Lestrade texted the following morning Sherlock and John wasted no time in jumping a cab to Scotland Yard; they were instructed to keep a low profile, and both wondered why they should be summoned with such secrecy.
John's lips quirked as they walked through the seemingly deserted outer office, for once he believed he had out-observed his friend, spotting several members of Greg's team hiding behind room dividers.
His smile however became strained as they walked into the Detective Inspector's office to find it decked out like Santa's grotto, with two costumes hanging by the window – one was obviously a Santa suit, the other a shapeless costume in varying green hues.
As they looked around they were joined by the team, led by Sally Donovan.
"Thought you might like some practice, John." she laughed, "So we got you a costume and one for your 'little helper'"
"Ah, that would explain the mess of green material." Sherlock's face was expressionless. "Not my colour I'm afraid, Sally."
"Aww, would you prefer brown and red? I'm sure we could…."
"Did Lestrade send for us just to do this?" John asked, disbelieving.
Sally waggled a mobile phone between slim fingers.
"He left it on his desk, irresistible."
Sherlock smile, a cold smile.
"I wonder how irresistible you will find being back on the beat?"
