Sherlock Help

[Leahbee5]

Hello I was wondering, I was watching Season 2 episode 1 of Sherlock again and still can't catch what Sherlock said before he, Watson, and The Lady ducked, it was right after he opened the lock. Thank you ahead of time for the answers

Was it "Vatican Cameos"

Watch it again with subtitles - and hope they're right!
