👀 SPOILER-FREE SUMMARY

A standalone filler mystery that takes Conan, Ran, and Sonoko out of their usual urban setting and drops them into a greenhouse filled with rare cacti and even rarer family secrets. The tone leans into classic Conan territory: a contained location, a cast of suspects with competing motives, and simmering tension beneath polite facades. Expect familial discord to drive the central puzzle, with the greenhouse's eccentric owner, his sons, and a housekeeper all hiding something. Pacing is steady rather than explosive—this is a deduction-focused episode that rewards attention to detail over action spectacle. The comedic beats between Sonoko and the core trio keep things from getting too heavy. If you enjoy the series' bread-and-butter one-off cases built on observational sleuthing and character interplay, this delivers exactly that without any larger narrative stakes.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Botanical Garden Arrival

Conan and the Detective Boys tour the botanical garden's prized cacti collection, meeting the botanists gearing up for an upcoming exhibition. The group dynamic among the staff already hints at something off beneath the surface.

Botanist Found Unconscious

The visit turns dark when one of the botanists is discovered collapsed near a rare cactus specimen, with clear signs of foul play. Conan immediately shifts into detective mode, examining the scene before anyone can tamper with evidence.

Staff Tensions Exposed

Conan's pointed interviews with the remaining staff crack open long-simmering rivalries and professional jealousies. Each botanist has a reason to resent the victim, and none of their alibis hold up cleanly under scrutiny.

The Stolen Specimen Secret

Conan digs up a buried incident — a valuable cactus specimen was stolen from the garden years ago, and the fallout from that theft still poisons relationships among the current staff. This old wound connects directly to the present attack.

A Second Disappearance

Just as Conan starts narrowing suspects, another staff member vanishes from the garden entirely, escalating the case from an isolated assault to something far more dangerous. The disappearance suggests the culprit is still active and desperate to cover their tracks.

📍 ARC CONTEXT

Coming off the two-part 'Nagasaki Mystery Theater' arc, this episode is a breather—a pure filler case with no connection to the Black Organization storyline or any recurring plot threads. It functions as a palate cleanser between more serialized content, offering a self-contained mystery typical of Conan's episodic format at this stage in its massive run.
