Question: How many years had Kingston Hospital been around for the year Shaw was born? Passage 1:When the war ended, he returned to the Keystone Agency and travelled all over Europe as a freelance reporter. It was during one of these trips that he came up with the idea for his first thriller, The Night of Wenceslas (1960). The novel is set in Czechoslovakia during the Cold War, and tells the story of young Nicolas Whistler, a 24-year-old Londoner whose business trip to Prague goes horribly awry. The Night of Wenceslas was an instant success, inviting favourable comparisons with such luminaries as Eric Ambler. Davidson became one of the handful of living writers to have their first novel appear in a green Penguin jacket. The book won the Crime Writers' Association's Gold Dagger Award (the top prize for crime and spy fiction in Britain) as well as the Authors' Club First Novel Award. It was filmed as Hot Enough for June (1964), with Dirk Bogarde in the role of Whistler.
 Passage 2:The year 2007 saw Dessay premiering Laurent Pelly's production of La fille du régiment at the London Royal Opera House in January and the Vienna State Opera in April. She performed the title role in Manon at the Liceu in Barcelona in June/July and opened the season at the Metropolitan Opera in the new Mary Zimmerman production of Lucia di Lammermoor. She returned in the same season to sing Lucia again and subsequently reprised in Pelly's production of La fille du régiment. She went on performing Lucia at the San Francisco Opera and a joint concert with tenor Jonas Kaufmann at Le Corum in Montpellier as part of the Festival de Radio France et Montpellier. In October, she sang Manon at the Lyric Opera of Chicago.
 Passage 3:Shaw was born on 13 July 1930 to Lieutenant Colonel W. A. Shaw, MC and Mrs E. Shaw (née Malley). Between 1943 and 1948, he was educated at Epsom College, a public school in Epsom, Surrey.
