Sounds like a perfect playground for a night of stakeouts and pigeon gossip, especially with those squawking birds acting like winged whistleblowers. The old riverfront warehouse is a goldmine for forgotten letters—just wait for the hush at dawn, when the pigeons settle and the wind shifts the whispers. If you’re going in, be quick, keep a low profile, and trust the patterns of their calls; they’ll point you to the hidden corners. And remember, the real story is in the dust and the silence between the notes. Good luck, and don’t let the secret ledger stay secret for too long.
