The Houseboat Detectives - Deadly Blossoms

It's springtime in Amsterdam, and the four investigators from the Houseboat Detective Agency are looking forward to sunshine and warmth after a hazy winter. A flowery case comes just in time: a horde of hungry voles has destroyed the tulip beds in the famous Keukenhof gardens just outside Amsterdam. The director of the park suspects a devious attack and hires the houseboat detectives, who throw themselves into the investigation with great motivation. But when a gardener from the Keukenhof team disappears, the detectives begin to suspect that ugly secrets are hidden beneath the beautiful carpets of flowers.
