The Irregulars is a British mystery adventure crime drama television series created by Tom Bidwell for Netflix.

[4] A group of teenagers living on the streets of Victorian London known as the Irregulars work for John Watson to solve increasingly supernatural crimes, while they search for Sherlock Holmes.

When Jessie wanders off one night in a dreamlike state, she is nearly hit by a carriage carrying Leopold, Queen Victoria's youngest son.

John Watson, a resident of 221B Baker Street, hires Bea and her friends to investigate the abduction of four newborn babies.

Spike leads Bea and Billy to the missing sister of an abducted baby, but they are attacked by an immense flock of birds which kill the girl.

On 20 December 2018, it was announced that Netflix was planning a series with Tom Bidwell based on the Baker Street Irregulars.

Tom Bidwell (who had directed Netflix's Watership Down) described the program as "my dream project and my oldest idea"[17] and it takes a different view of Holmes and his relationship to the Irregulars.

In December 2019 the cast was announced as Henry Lloyd-Hughes in the role of Sherlock, Royce Pierreson as Doctor Watson, and Clarke Peters as Linen Man, Thaddea Graham as Bea, Darci Shaw as Jessie, Jojo Marcari as Billy, McKell David as Spike, and Harrison Osterfield as Leopold.

[19][2] In September, 2020 it was announced that Aidan McArdle had joined the cast in the role of Inspector Lestrade along with Olivia Grant as Patricia Coleman-Jones.

[26] Filming was temporarily disrupted in January 2020 when a cast member was injured on set on Liverpool's Ormond Street.

The website's critics consensus reads, "It taps into some fairly regular plot points, but when it dares to defy expectations and focus on its charming young cast, The Irregulars hints at something truly special lingering beneath the surface.
