It started well. A foot chase through London back alleys. Sherlock and John enjoyed the pursuit.
It went completely sideways. An ambush in a cul-de-sac. The only way out was up a stone wall or through a line of thugs.
It looked hopeful. An unexpected outlet! Unfortunately, it fed into the Thames.
It came together. A narrow escape with the aid of Scotland Yard. A police boat dragged them both from icy waters.
It finished satisfactorily. Apprehended criminals. Lestrade shoved the smugglers into the squad himself.
Epilogue. Hot tea and cosy blankets in 221B. "All's well that ends well, right?"
