Michael Redhill (born 12 June 1966) is an American-born Canadian poet, playwright and novelist. Born in Baltimore, Maryland, Redhill was raised in the metropolitan Toronto, Ontario area. He pursued one year of study at Indiana University, and then returned to Canada, completing his education at York University and the University of Toronto. He was on the editorial board of Coach House Press from 1993 to 1996, and was the publisher of the Canadian literary magazine Brick from 2000 to 2009.
In 2012, he revealed that he is also the author of three novels published under the name Inger Ash Wolfe.
His play, Building Jerusalem, depicts a meeting between Karl Pearson, Augusta Stowe-Gullen, Adelaide Hoodless, and Silas Tertius Rand on New Year's Eve night just prior to the 20th century.
The publishers had stated that Ash is "the pseudonym for a well-known and well-regarded North American literary novelist," after the publication of the first mystery by Wolfe in 2008. The pseudonym was originally to be Inger Wolf until it was recognized that a Danish crime writer already uses that name.
As Wolfe, Redhill published his first mystery novel The Calling in 2008, released simultaneously in Canada, the United States and the United Kingdom. While the book has received good reviews, speculation as to the author's real identity played a large role in many of the reviews. Canadian reviewers suggested Linda Spalding, Michael Redhill, Jane Urquhart and David Adams Richards, among others. American reviewers suggested Margaret Atwood, and Farley Mowat. UK critics did not write about the issue.
