If you love cosy crime dramas like Shakespeare & Hathaway: Private Investigators and Murder, She Wrote, you might want to add this witty and clever series to your watchlist this week. But first, find out more about the show below.

What is Harry Wild about? 

Jane Seymour stars as literature professor Harriet 'Harry' Wild, who is settling into a life of retirement when she's mugged. While recovering at the home of her son Charlie (Kevin Ryan), a detective in the Dublin police, Harry picks up a clue for his current case. But when she's rebuffed, Harry decides to investigate the crime herself. 

Recruiting an unlikely young sidekick, Fergus Reid (Rohan Nedd), Harry finds a new path as a private investigator.

In season four, business is booming at the Wild/Reid Detective Agency as Harry and Fergus  welcome an unexpected client: Charlie Wild (Kevin Ryan, Copper).

Elsewhere in the series, Harry is hired by a friend and former wild child, while a Dublin literary tour takes a bloody turn. 

What have viewers said about the show? 

The series has been hailed as "brilliant" and a "must-watch" by fans on social media.

A third viewer hailed the show as a "gem," adding: "This series delivers it all; comedy, mystery and heart in a well-acted and filmed package."

Will there be a fifth season? 

Fans will be pleased to know that the Dublin-set drama will return with a fifth season, which began filming in September last year.
