John thought there were some things that Oliver should see that were not about murder. Oliver knew everything about every single interesting murder scene in Britain, but John thought maybe he should see some cathedrals, too.
“Cathedrals are boring,” Sherlock complained.
“Look at the stained glass.” John pointed for Oliver’s benefit. “Stained glass is beautiful artistry. These windows date back to medieval times.”
“Boring!” Sherlock called back to them, as he walked along the pews. Then he paused saying, “Hmm. Except this one’s full of poisonous plants. Do you think the artist killed someone?”
Oliver ran over delightedly to see.
