“We are interested in the offer and intrigued,” said Seth Miller of the Grand Theatre in Salt Lake City. But Rudin has yet to respond to questions that would need to be answered first, including how long the offer is good for, Miller said Saturday.

Later, in the same article:

Rudin had defended his original position in a recent statement: “We hate to ask anybody to cancel any production of a play anywhere, but the productions in question as licensed by DPC infringe on rights licensed to us by Harper Lee directly,” he said. “The Sergel play can contractually continue to be performed under set guidelines as described in detail in its own agreement with Harper Lee — and as long as those guidelines are adhered to, we have no issue with the play having a long life.”

That sparked an online revolt with the rallying cry of #BoycottRudinplays. Chris Peterson, founder of the OnStage Blog, asked ticket buyers to avoid all current and coming Rudin productions on Broadway, including “Hillary and Clinton,” ”Gary: A Sequel to Titus Andronicus,” ”King Lear,” ”The Ferryman” and “The Book of Mormon.”

Follow the money.

and send investigators to see if there were any earlier versions, also any papers of her sister Alice Lee (lifelong companion and manager) casting light on Harper’s posthumous intentions for her work.

The questionable doings in Harper Lee’s final years (2007-2016) are covered in her Wikipedia article.

For many decades, Harper “Nelle” Lee relied on her older sister Alice Lee, an attorney. Alice shielded Harper’s privacy while maintaining a respectful relationship with their community and the “Mockingbird” fan base, allowing “Mockingbird” to ripen into a deeply beloved national treasure. Unfortunately, Harper had a stroke in 2007 and Alice became incapacitated in 2011.

A new lawyer took charge of Harper’s affairs and started filing lawsuits. (She would retain control of the estate after Harper’s death in 2016.) It was this new lawyer’s decision to market an inferior first draft of “Mockingbird” as a supposed sequel “Go Set a Watchman” (2015). It brought in money (not really needed), but at cost to Harper Lee’s literary reputation. In 2016, the estate would block further printing of an economical “mass market” paperback of the book, which had made it an attractive choice for cash-strapped school systems and classes.

It would be an appealing morality tale (like “Mockingbird” itself?) if proper investigation and legal action could restore “Mockingbird” to the millions who have loved it.
