From 1971's "Andromeda Strain" to "Jurassic Park" and, most recently, "Prey," Michael Crichton's novels have racked up millions in sales. But the bestselling author would prefer that his personal life not speak volumes, it seems.

The author, 60, sued his estranged wife and her lawyer on Thursday, claiming they violated a confidentiality deal that was part of the couple's pending divorce, Reuters reports.

Anne-Marie Crichton filed for divorce from the Harvard med school graduate and "ER" co-creator in September, after 13 years of marriage. Proceedings were apparently supposed to be kept hush-hush, but now Crichton claims that attorney Stephen Kolodny made statements on television earlier this month about the couple's marriage and about Crichton's relationship with his 13-year-old daughter.

The writer also is claiming that Anne-Marie knew about Kolodny's plans to discuss the divorce, and gave him the thumbs-up, according to Reuters.

In September -- shortly after the divorce filing -- two masked men broke into Crichton's home in suburban Santa Monica, tied up the author and his daughter and stole undisclosed personal items. Crichton and his daughter were unharmed.
