Some context: Samuel Luther "Big Sam" Thompson (March 5, 1860 - November 7, 1922) was an American professional baseball player from 1884 to 1898 and with a brief comeback in 1906. At 6 feet, 2 inches, the Indiana native was one of the larger players of his day and was known for his prominent handlebar mustache. He played as a right fielder in Major League Baseball for the Detroit Wolverines (1885-88), Philadelphia Phillies (1889-1898) and Detroit Tigers (1906). He was inducted into the Baseball Hall of Fame in 1974.
At age 36, Thompson played his last full season of professional baseball in 1896. His average dipped to .298, but he still managed to collect 100 RBIs. Thompson's throwing remained strong as he turned in one of the finest defensive performances of his career. Despite appearing in only 119 games in the outfield, he led the league in outfield fielding percentage (.974), outfield assists (28), and double plays from the outfield (11). One sports writer noted that, even at age 38, Thompson "possessed an arm that the fastest sprinters in the big league had a lot of respect for." As a team, however, the Phillies fell to eighth place in the National League with a 62-68 record.  In 1897, at age 37, Thompson was sidelined by pain and appeared in only three games. Some accounts suggest that Thompson's absence from the lineup may have also been the result of his not getting along with Philadelphia's new manager George Stallings. Without Thompson, the 1897 Phillies dropped to 10th place with a 55-77 record.  Before the 1898 season began, Thompson gave an interview in which he questioned the Phillies chances to compete in 1898: "What are the Phillies' chances this season? Six clubs, Cincinnati Baltimore, Boston, New York, Cleveland and Brooklyn are bound to beat them, and they will have to fight hard to lead the second division, and I very much doubt if they can do that." Though his loyalty to the Phillies was questioned, Thompson did return in 1898 and was batting .349 with 15 RBIs, five doubles, three triples, a home run after 14 games. However, Thompson opted to leave the team in May 1898 and return to his home in Detroit. His sudden retirement has been attributed to a "combination of homesickness and chronic back pain." Other accounts indicate that continued tension with manager Stallings contributed to Thompson's decision to retire.

Some context: Zorro (Spanish for "fox") is a fictional character created in 1919 by American pulp writer Johnston McCulley, and appearing in works set in the Pueblo of Los Angeles during the era of Spanish California (1769-1821). He is typically portrayed as a dashing masked vigilante who defends the commoners and indigenous peoples of California against corrupt and tyrannical officials and other villains. His signature all-black costume includes a cape, a hat known as sombrero cordobes, and a domino mask that covers the upper part of his face. In the stories, Zorro has a high bounty on his head, but is too skilled and cunning for the bumbling authorities to catch, and he also delights in publicly humiliating them.
In The Curse of Capistrano, Senor Zorro became an outlaw in the pueblo of Los Angeles in California "to avenge the helpless, to punish cruel politicians, to aid the oppressed." He is the title character, as he is dubbed the "Curse of Capistrano". The novel features extensively both Don Diego Vega and Zorro, but the fact that they are the same person is not revealed to the reader until the end of the book. In the story, both Diego and Zorro romance Lolita Pulido, an impoverished noblewoman. While Lolita is unimpressed with Diego, who pretends to be a passionless fop, she is attracted to the dashing Zorro. The main villain is Captain Ramon, who also has his eyes on Lolita. Other characters include Sgt. Pedro Gonzales, Zorro's enemy but Diego's friend; Diego's deaf and mute servant Bernardo; his ally, Fray (Friar) Felipe; his father Don Alejandro Vega, the richest landowner in California and a widower; Don Carlos Pulido and his wife, Dona Catalina, Lolita's parents; and a group of noblemen (caballeros) who, at first, hunt Zorro but are then won over to his cause.  In later stories, McCulley introduces characters such as pirates and Native Americans, some of whom know Zorro's identity.  In McCulley's later stories, Diego's surname became de la Vega. In fact, the writer was wildly inconsistent. The first magazine serial ended with the villain dead and Diego publicly exposed as Zorro. But in the sequel, the villain was alive and the next entry had the double identity still secret.  Several Zorro productions have expanded on the character's exploits. Many of the continuations feature a younger character taking up the mantle of Zorro.  McCulley's stories are set during the during the era of Spanish California (1769-1821) and, although exact years are often vague, the presence of the Pueblo of Los Angeles means the stories cannot happen before 1781, the year it was founded. Some media adaptations of Zorro's story have placed him during the later era of Mexican California (1821-1846).
