Dr. Malows hemmelighed

Dr. Marlow synes at være en excentrisk havefanatiker. Han er i sin have hver eneste dag, og på regnvejrsdage arbejder han i sine to drivhuse.
Haven er fuld af roser og liljer, og desuden dyrker han kartofler, tomater og gulerødder. Han hader skadedyr, og han har derfor altid meget gift i huset. Og der er aldrig lus på roserne, og bladene er altid grønne.
Græsplænerne er hans stolthed. De er så fine at hverken børn eller voksne må gå på dem. Men hvorfor forsøger han at holde folk væk fra sin have? Frygter han, at børnene vil lukke hans gæs ud af burene? Eller at de vil fange hans guldfisk og stjæle hans tomater? Nej. Der må være en anden forklaring. Dr. Marlow har været gift 3 gange. Men hvor er hans koner? De var alle rige kvinder. Skjuler dr. Marlow noget i drivhusene eller under buskene?

engelsk:
Dr. Marlow’s secret

Dr. Marlow seems to be an eccentric garden fanatic. He is in his garden every day, and on rainy day he works in his two greenhouses.
The garden is full of roses and lilies, and besides that he grows potatoes, tomatoes and carrots. He hates vermin and therefore he always has a lot of poison in the house. And there are never lice on the roses, and the leaves are always green.
The lawns are his pride. They are so fine that neither the children nor the adults are allowed to walk on them. But why is he trying to keep people away from his garden? Does he fear that the children will let his geese out of the cages? Or that they will catch his goldfish and steel his tomatoes? No. There’s got to be another explanation. Dr. Marlow has been married 3 times. But where are his wives? They were all rich women. Is Dr. Marlow hiding something in the greenhouses or under the bushes?
