Predictably Sherlock got bored of being a lookout rather quickly and instead set to work unlocking Kilmov's phone. There was a pass code which he cracked quickly by tilting the phone to the light and using the tell-tale grease smear on the screen. There was nothing happening at the front of the house so he set to work reading Kilmov's texts and emails, although it was soon apparent that he kept a separate email address and password protected inbox for any 'business' matters.
The gang cleared out after about 20 minutes, apparently finding nothing of interest, and left grumpily from the building, leaving the front door wide open and the place trashed. Amateurs, Sherlock smirked to himself.
When the coast was clear he emerged from his hiding place, scrolling down Kilmov's lists of contacts as he made his way to get John. It all looked pretty routine, a few friends who most likely weren't smuggling related, parents, aunt, and then 'work'. Tapping the the screen quickly Sherlock dialled 'work' and held the phone to his ear. The call went through quickly to answer phone and the crackling voice of a old women came through.
"Hello, you've reached St. Micheal's Parish Church, please leave a message and we'll get back to you as soon as possible."
Sherlock cocked an eyebrow in thought for a second in thought before shouting out loud.
"Yes! Oh it's so obvious!"
He rounded the street corner quickly, bumping into an excited but flustered looking John. He grabbed his friend by the shoulders and steered him away from the house before he could protest.
"I can't believe I didn't see it before John" he started as they strode up the street.
