What does Spade say Brigid, Cairo and Gutman do aboard the La Paloma?

Spade tells Effie`Brigid was indeed at the La Paloma along with Cairo and Gutman. Apparently Brigid spent some time with the ship's captain, Jacobi, before Cairo, Gutman and Gutman's gunman arrived. A watchman reported that the captain and his four guests left the ship at midnight.
