She went for a quick sandwich at Euston Station and lost a million pound violin.
The thief who stole it tried to sell it for a hundred quid.
Now three years on and an international search later the violinist and her precious violin are soon to be reunited.
Elodie Harper has more.
British Transport Police released this image of the violin, after it had been recovered.
Min-Jin Kym spoke to the British Transport Police about her emotions following the recovery of her £1.2m violin.
Internationally-acclaimed musician Min-Jin Kym said that she was elated by the news of the violin's recovery.
"It's been a very difficult journey; I still can't quite believe what has happened," she said.
"The loss of the instrument, and the acute responsibility I felt, was at the back of my mind at every moment of the day.
"I'd played the instrument since I was a teenager, so it'd been a huge part of my identity for many years.
"The theft was a crushing blow and the detectives in the case had always, quite rightly, been very careful not to give me false hope.
"When they told me the good news, it didn't feel real.
"I've now gone from devastation to the other end of the scale - an incredible feeling of elation that hasn't left me. I'm still feeling the butterflies in my stomach and am on cloud nine."
Detective Chief Inspector Simon Taylor, who led the hunt for the violin, said:
A 300-year-old Stradivarius violin, which was stolen at Euston Station in 2010 has been found in the Midlands.
The instrument, which is worth £1.2 million, was taken by opportunistic thieves while musician Min-Jin Kym was eating at a Pret a Manger cafe.
Three people were convicted in connection with the theft in 2011, but the violin had not been recovered until now.
The instrument was found intact, with some very minor damage, in its case along with one bow valued at £62,000 and another valued at more than £5,000.
Experts have verified that it is the genuine article and the violin is now being held at a secure London location.
