beard the lion in his den and beard someone in his den
Prov. to confront someone on his or her own territory. I spent a week trying to reach Mr. Toynbee by phone, but his secretary always told me he was too busy to talk to me. Today I walked straight into his office and bearded the lion in his den. If the landlord doesn't contact us soon, we'll have to beard him in his den.
