Can you explain the significance of London in the stories about Sai Baba's devotees? I heard he sent someone there for a task.

The provided texts do not contain any reference to London or Sai Baba sending any devotees to such a distant city. Instead, Chapter 18 details how Baba's grace extended to devotees whether they were near him or in a 'distant land,' emphasizing his closeness within their hearts rather than physical travel. The chapter focuses on Baba's practice of assigning readings of sacred texts like the Jnaneshwari and Nath Bhagawat to devotees such as Sakharam Hari Jog in Shirdi. This method of bestowing grace and instruction through scriptural study in Sathe's Wada was a primary focus, and there is no mention of missions to international locations like London.
