The production company, Tuesday’s Child Television, has hired Sara Pascoe to host Guessable, an eight-part series in which two teams compete to identify a mystery item, which could be the name of a famous person or an object, hidden inside a sealed box. Pascoe will co-present with John Kearns (Top Coppers) while Alan Davies, a regular on QI and stand-up comedian Darren Harriott are opposing team captains.
