An innocuous message card pinned to an Italian university notice board led British student Meredith Kercher to her pointless and savage death.
Like thousands of young Britons each year, she had set off ready for an adventure during her 12 months abroad studying.
The 21-year-old, from Coulsdon in Surrey, was reading European Studies at Leeds University and was due to spend a year in Italy as part of an EU-wide scheme which lets students take part of their degree in another country.
It did not take her long to fall in love with the picturesque Umbrian hilltop city of Perugia, where she had chosen to spend the academic year 2007/08.
On arrival, she checked into a local hotel while she looked for somewhere to live.
On a notice board at the university she found the advert for a room in a large white house in the via della Pergola.
The house was situated at the top of a steep wooded valley, just below the level of a winding road near the city's historic centre.
It boasted panoramic views of Perugia, which appealed to Miss Kercher, and she moved in shortly afterwards.
At first she shared the house with two young Italian women.
But they were soon joined by a fourth housemate, Amanda Knox, a then 20-year-old foreign exchange student from Seattle.
Miss Kercher had come to Perugia to learn, and she worked hard at her studies in modern history, political theories and history of cinema at the city's University for Foreigners.
Intelligent, witty and caring, she was popular among her fellow students.
One of four children, she had been educated at the £10,000-a-year Old Palace of John Whitgift School, an independent girls' school in Croydon, and had always been hard working.
She hoped either to become a journalist when she graduated or to work in Brussels.
But as well as being conscientious and ambitious, she was a sociable and popular student who was also in Italy to enjoy herself.
One of the reasons she had chosen Perugia was its annual chocolate festival, during which many of the streets within the city walls are lined with stalls and packed with visitors.
She had been enjoying herself at the festival in the final days of her life.
In a message to a friend posted on social networking site Facebook she wrote: ''I'm having a good time thanks, it's starting to get really cold now, but the chocolate festival is on at the moment, so a good excuse to drink a lot of hot chocolate.''
On October 31 she attended a Halloween party dressed as a vampire with fake blood coming from her mouth.
The next day she called her mother Arline, as she did every day, to discuss plans for her return to England.
She told her she was tired after coming back late from the party the night before and that that night she was going to watch a film with some friends.
She planned to come back early as she had an essay to finish.
She also had lectures at 10am the next day and exams approaching.
But the next day, November 2 2007, she was found dead in her room.
Her throat had been slit and her semi-naked corpse was covered by a duvet.
