Guthrie joined the WSPU at the age of 18.[2] She was arrested during Black Friday on 18 November 1910 and twice during 1911.[3]
In 1912, she took part in a window-smashing raid, breaking the shop windows of the famous jewellers Garrard & Co of Ablemare Street, London.[4] She was sentenced to six months imprisonment in HM Prison Holloway.[5]
During her time in prison, she contributed to Holloway Jingles, a book of poetry which was published by the Glasgow branch of the WSPU. Her poem To D.R. is thought to be dedicated to fellow suffragette Dorothea Rock.[6]
After her release from prison Guthrie worked as an actor, using the stage name Laura Grey. Her first performance was in the pantomime "The forty thieves" at the Lyceum Theatre in 1912.[2]
Death
Guthrie died at the age of 25, at 111 Jermyn Street, St James's, Westminster, leaving an estate valued at £1564.[8] The cause of death was taking an overdose of veronal, which shocked society. A poem about her was published in the "Daily Herald" newspaper in June 1914.[9] According to the website "Woman and her sphere", the poem was written by Anna Wickham.
