Kat Lind, an American expatriate living in London with her entrepreneur husband and their young son, attends an opening at a prestigious Mayfair art gallery and is astonished to find her own face on the walls. The portraits are evidence of a long-ago love affair with the artist, Daniel Blake. Unbeknownst to her, he has continued to paint her ever since. Kat is seduced by her reflection on canvas and when Daniel appears in London, she finds herself drawn back into the sins and solace of a past that suddenly no longer seems so far away.

When the portraits catch the attention of the public, threatening to reveal not only her identity, but all that lies beyond the edges of the canvases, Kat comes face to face with the true price of their beauty and with all that she now could lose.

Moving between the glamour of the London art world and the sensuous days of a love affair in a dusty Paris studio, life and art bleed together as Daniel and Kat's lives spin out of control, leading to a conclusion that is anything but inevitable, in Mary Waters-Sayer's The Blue Bath.
