“When the idea came about to create this crossover event for fans, ourwriters' roomwas immediately energized. The creative freedom to merge these two worlds which, at face value, seem so different; but at their core have such striking similarities - mystery, intrigue and methodical deduction, wrapped up in such strong character partnerships - was a challenge that we all welcomed, and we believe that fans of both series will be very satisfied by the result.
