Greg Mortenson with his wife and daughter at the Khyber Pass. (Penguin Books)

Things aren’t looking good for Greg Mortenson, the once-celebrated ”Three Cups of Tea” author. Ten months ago “60 Minutes” and writer Jon Krakauer accused Mortenson of using the Central Asia Institute — his educational charity — as his personal piggy bank. Now Outside Magazine reexamines the case: An ongoing investigation by Montana’s attorney general and a pending civil suit charging that Mortenson, his affiliates and even Penguin Publishing conspired to sell books and solicit donations based on “outright lies,” which yielded millions of dollars from unsuspecting readers. (The publisher, which promised to review the materials when the story broke, now contends in court filings that it “owes no duty to verify the accuracy” of nonfiction books unless libel is involved.) Mortenson, who originally cited health problems for his lack of response, hasn’t spoken publicly about the allegations since last April.
