Prior to taking over from Lynda Lee-Potter at the Daily Mail, Pearson was a columnist with London’s Evening Standard and The Daily Telegraph. She began her career with the Financial Times, where she was a sub-editor, before moving to The Independent and then The Independent on Sunday in 1992. There she was assistant to Blake Morrison before becoming a TV critic, winning the award for Critic of the Year at the British Press Awards in 1993. Pearson has presented Channel 4’s J’Accuse; BBC Radio 4’s The Copysnatchers and participated as a panellist on Late Review, the predecessor of Newsnight Review.

Pearson is the author of a novel, I Don’t Know How She Does It (2002), a “chick lit” examination of the pressures of modern motherhood.

She has since written I Think I Love You (2010), a novel about a teenager’s passion for David Cassidy in the 1970s, and the man who is responsible for writing the so-called replies from David Cassidy to the teenage fans, two characters who later meet up again twenty years after experiencing marriage, divorce, and children. The Telegraph praised the novel for its warmth and sincerity;[16] The Guardian declared it an “unrealistic and sappy romance”.

A sequel to I Don’t Know How She Does It was announced in 2015 and published in September 2017. The novel, How Hard Can It Be, continues the story of the protagonist Kate Reddy, now approaching 50 and struggling with bias against older women in the workplace. The book, which attracted considerable publicity but failed to reach bestseller status, is published by Borough Press in the U.K. It will be published by St. Martin’s Press in the U.S., with a release date of June 2018
