The Princess Pat is an operetta in three acts with music by Victor Herbert and book and lyrics by Henry Blossom.

[2] After an Atlantic City, New Jersey tryout in August 1915, The Princess Pat was scheduled to make its Broadway debut on September 27, 1915.

[1] However, the opening was postponed for two days when the actress Angela Palmer (born Pearl Foster), who was scheduled to perform the important ingenue role of Grace Holbrook, was murdered by her boyfriend on September 26.

Pat loves her husband but was unhappy living in Sicily where she was homesick for her Easthampton, Long Island home, and her beloved dogs and horses.

Assisted by New Yorker Bob Darrow, Pat comes up with a plan to make her husband jealous: she pretends to elope with Schmalz.
