A Tasmanian woman has discovered a love letter written by a former prime minister in her living room.
Ros Mills bought a cottage in Deloraine that was rented by Joseph Lyons and his wife Dame Enid during the early years of their marriage.
While having a wood heater installed, Ms Mills found behind the mantelpiece a letter dated 1918, when Mr Lyons was working in Hobart as a state MP.
Ms Mills says the letter expressed Mr Lyons' love for his wife and his desire to be home while she was pregnant with their second child.
"I love you with all my heart and soul and I hate to be away," Mr Lyons wrote.
He became prime minister in 1932 and in 1943 Dame Enid was the first woman elected to the House of Representatives.
Mr Lyons is the only Tasmanian to serve as prime minister.
"I was very excited by the fact that she'd lived in the house with her little boy and when she was pregnant," Ms Mills said.
"You immediately put it into your own context.
"I thought 'gosh, this letter's been here since before I was born' and given I'm nearly 74 that seemed a long time ago."
The letter has been donated to the National Trust and will be kept at Home Hill, the couple's main residence in Devonport.
Ann Teesdale from the National Trust says their life was a true love story.
"Through all of the public life, they just loved to spend time together," she said.
