Its romance novel publishing division Harlequin posted a surprising drop, said David Holland, president and chief executive of the Toronto-based company. “We had anticipated lower earnings at Harlequin but not to this extent,” Mr. Holland said during a conference call with analysts. “Lower volumes, including a deterioration in overseas volumes, which we were concerned about in the last quarter, were responsible for the shortfall to expectations.” It is unclear how the Kindle and Kobo phenomenon have impacted Harlequin.
