Netflix could step in to rescue Longmire, the fan-favorite crime drama canceled in late August by A&E after three seasons.

Deadline reports the streaming service is in "deep negotiations" with Warner Horizon Television to continue the series, based on the bestselling mystery novels by Craig Johnson.

However, the website notes that sources indicate the talks "have been tricky, and there is a chance that a final agreement may not be reached, though there is a will on both sides and insiders are hopeful." If a deal pans out, the fourth season would likely begin production in March.

Longmire starred veteran Australian actor Robert Taylor as Walt Longmire, a rugged Wyoming sheriff who refused to move on following his wife's death; his pursuit of her killer continued throughout the series, reaching a climax in the Season 3 cliffhanger. Katee Sackhoff, Lou Diamond Phillips and Bailey Chase also starred.
