Problem: Blood, Sweat & Tears (also known as "BS&T") is a jazz-rock American music group. They are noted for their combination of brass and rock band instrumentation. The group recorded songs by rock/folk songwriters such as Laura Nyro, James Taylor, the Band and the Rolling Stones as well as Billie Holiday and Erik Satie. They also incorporated music from Thelonious Monk and Sergei Prokofiev into their arrangements.

Clayton-Thomas left in early January 1972 to pursue a solo career. He was briefly replaced by Bobby Doyle and then Jerry Fisher, who went on to front the next incarnation of Blood, Sweat & Tears. Fred Lipsius left as well and was briefly replaced by Joe Henderson, before Lou Marini settled into the new lineup. Another founding member, Dick Halligan, also departed, replaced by jazz pianist Larry Willis (from the Cannonball Adderley Quintet), and Swedish guitarist Georg Wadenius, from the popular Swedish outfit Made in Sweden, joined as lead guitarist around the same time. The new edition of Blood, Sweat & Tears released New Blood in September 1972, which found the group moving into a more overtly jazz-fusion repertoire. The album broke through the Top 40 chart (the last BS&T LP to do so) and spawned a single ("So Long Dixie", chart peak: 44) that received some airplay. Also included on the record was a cover version of Herbie Hancock's "Maiden Voyage", featuring the voice/guitar soloing of Georg Wadenius. In mid-1973, Katz left to pursue a career as a producer (for Lou Reed and others). Winfield departed as well and was replaced by Tom Malone. Blood, Sweat & Tears' next album, No Sweat (June 1973), continued in a jazz-fusion vein and featured intricate horn work. Tom Malone's stay in the band was brief and he left to make way for jazz trumpeter John Madrid. But Madrid's tenure was likewise short-lived and he never recorded with the band. Both Madrid and Soloff left in early 1974, making way for new horn player/arranger Tony Klatka on their next release, Mirror Image (July 1974), which also saw the addition of vocalist/saxophonist Jerry LaCroix (formerly of Edgar Winter's White Trash), sax player Bill Tillman, bassist Ron McClure and the exodus of original bass player Jim Fielder. This recording features the adoption of a sound pitched between Philly Soul and the mid-1970s albums by Herbie Hancock's Headhunters, along with aspirations to Chick Corea's jazz-fusion group Return to Forever. Jerry LaCroix left BS&T to join Rare Earth after playing his final show with them at Wollman Rink in New York's Central Park on July 27, 1974. Luther Kent, a blues singer from New Orleans, was recruited to replace LaCroix.

Problem: Georgette Heyer (; 16 August 1902 - 4 July 1974) was an English historical romance and detective fiction novelist. Her writing career began in 1921, when she turned a story for her younger brother into the novel The Black Moth.

Heyer was born in Wimbledon, London, in 1902. She was named after her father, George Heyer. Her mother, Sylvia Watkins, studied both cello and piano and was one of the top three students in her class at the Royal College of Music. Heyer's paternal grandfather had emigrated from Russia, while her maternal grandparents owned tugboats on the River Thames. Heyer was the eldest of three children; her brothers George Boris (known as Boris) and Frank were four and nine years younger than her. For part of her childhood, the family lived in Paris but they returned to England shortly after World War I broke out in 1914. Although the family's surname had been pronounced "higher", the advent of war led her father to switch to the pronunciation "hair" so they would not be mistaken for Germans. During the war, her father served as a requisitions officer for the British Army in France. After the war ended he was appointed a Member of the Order of the British Empire (MBE). He left the army in 1920 with the rank of captain, taught at King's College London and sometimes wrote for The Granta. George Heyer strongly encouraged his children to read and never forbade any book. Georgette read widely and often met with her friends Joanna Cannan and Carola Oman to discuss books. Heyer and Oman later shared their works-in-progress with each other and offered criticism. When she was 17, Heyer began a serial story to amuse her brother Boris, who suffered from a form of haemophilia and was often weak. Her father enjoyed listening to her story and asked her to prepare it for publication. His agent found a publisher for her book, and The Black Moth, about the adventures of a young man who took responsibility for his brother's card-cheating, was released in 1921. According to her biographer Jane Aiken Hodge, the novel contained many of the elements that would become standard for Heyer's novels, the "saturnine male lead, the marriage in danger, the extravagant wife, and the group of idle, entertaining young men". The following year one of her contemporary short stories, "A Proposal to Cicely", was published in Happy Magazine.
