Intelligence; music by Jake Heggie, libretto by Gene Scheer, is, on the face of it, a spy thriller. We are in Richmond in 1865 and Union forces are closing in on the Southern capital. Elizabeth Van Lew is a wealthy spinster who is spying for the North. She infiltrates her enslaved woman Mary Jane Bowser into the Jefferson Davis household but Mary Jane is not what she appears. She is highly intelligent, literate and has a photographic memory. No-one will think to hide sensitive information from a, presumed illiterate, slave. The relationship between the two women is complex. Mary Jane was born in Elizabeth’s father’s home but was baptised in the white church and educated in the north. She has been told that her mother died in childbirth. But all is not as it seems.
