Miss Scarlet and the Duke: Season 6 Guide, Cast, Streaming

When a detective drama loses its male lead halfway through, most fans brace for cancellation. But Miss Scarlet and the Duke has done something unexpected: it kept going — and landed a sixth season. This guide covers why the Duke left, what Season 6 brings, and where to stream every episode.

Creator: Rachael New ·
Network: PBS (Masterpiece) ·
Premiere: 2020 ·
Lead actress: Kate Phillips

The table below sums up the show’s identity, from its Victorian setting to its current season count.

Why is the Duke no longer on Miss Scarlet?

Stuart Martin played Inspector William Wellington — the Duke — from Season 1 through Season 4. The character left the show at the end of Season 4 (PBS Masterpiece series page). Martin’s departure was due to other acting commitments, though the show’s creator Rachael New has not publicly detailed the exact reason.

Will Stuart Martin ever return to Miss Scarlet and The Duke?

As of 2025, there is no official confirmation of a return. PBS Masterpiece has not announced any plans to bring the Duke back, and Martin is not listed in the Season 6 cast (PBS Masterpiece Season 6 details).

The implication: the show is betting its future on Eliza’s solo appeal — a risk that has paid off so far with a sixth season pickup.

Will there be a season 6 of Miss Scarlet and The Duke?

Yes. Season 6 has been announced and is well into production. PBS Masterpiece confirmed that early streaming on PBS Passport begins December 7, 2025, with a broadcast premiere on January 11, 2026 (PBS Masterpiece official announcement).

Will there be a season 7 for Miss Scarlet?

Season 7 is not yet officially confirmed. PBS has not issued a renewal beyond Season 6, meaning the show’s future is uncertain past 2026 (Deadline).

Is Miss Scarlet renewed for Season 7?

No. As of early 2025, only Season 6 is confirmed. The show’s ratings and viewership on PBS Masterpiece and streaming will likely determine whether a seventh season is ordered (Parade).

The pattern: PBS is treating Miss Scarlet as a franchise worth investing in, despite losing its co-lead.

Is Miss Scarlet and The Duke on Netflix or Prime?

Miss Scarlet is a PBS Masterpiece series, so its primary home is PBS. Netflix does not currently carry the show in most countries (PBS Masterpiece). Amazon Prime Video offers seasons through the PBS Masterpiece add-on channel, but not included with a standard Prime subscription.

Where can I watch all seasons of Miss Scarlet?

• PBS.org and PBS app: Full seasons available with a PBS Passport membership (PBS Masterpiece)
• Amazon Prime Video: Via the PBS Masterpiece channel (separate subscription) (PBS Masterpiece)
• DVD/Blu-ray: Available for purchase through major retailers
• Not on Netflix: The show is not available on Netflix in the US or UK (Parade)

The trade-off: PBS Passport gives the most complete access, including early Season 6 streaming. Amazon Prime users need an extra subscription to watch.

Where can I watch all seasons of Miss Scarlet?

Full seasons are available on PBS.org with a subscription. PBS Passport members can stream all five current seasons. Amazon Prime Video may have limited episodes due to licensing — some users report missing episodes because of regional restrictions (PBS Masterpiece).

Why are episodes unavailable on Amazon Prime?

Episodes may be locked behind the PBS Masterpiece channel on Prime. Some episodes are missing from Prime’s catalog because of regional licensing deals that PBS negotiates separately. The most reliable way to watch all episodes is directly through PBS (Parade).

The catch: convenience comes with a price tag. No single streaming service covers all seasons in all regions without an add-on.

How old is Eliza Scarlet supposed to be?

Eliza Scarlet is in her late 20s when the series begins. The character was born around 1851 — implied by her father’s death in 1880 and Victorian norms for a woman of that era (PBS Masterpiece series page). Her age is not explicitly stated but is consistent with a woman in her late 20s to early 30s navigating a male-dominated profession.

Why this matters: Eliza’s relative youth makes her achievement as a female detective in 1880s London even more striking. The show uses her age to highlight both her vulnerability and her determination.

Quotes from the cast and creators

“Miss Scarlet Season 6 will be available to stream on PBS Passport starting December 7, 2025, with a broadcast premiere on January 11, 2026.”

— PBS Masterpiece press release (PBS Masterpiece)

“The new season brings a fresh dynamic to the series with a new detective inspector at Scotland Yard.”

— Deadline report on Season 6 cast (Deadline)

“Season 6 of Miss Scarlet and the Duke introduces Tom Durant-Pritchard as Alexander Blake and Sam Buchanan as George Willows.”

— Parade preview (Parade)

The editorial read: PBS is positioning the show for a new era without the Duke. The introduction of multiple new Scotland Yard characters signals a deliberate expansion of the supporting cast.

For fans waiting to see where Eliza goes next, the choice is clear: grab a PBS Passport membership and start streaming Season 6 on December 7, or wait for the broadcast in January. Miss Scarlet is far from finished.
