Green Thoughts [1932] – ★★★★
In this short story, Mr. Mannering receives a strange-looking, mysterious orchid root, plants it and sees it growing exponentially in time. He thinks that this is a new, yet undiscovered specimen, and is supremely happy. However, soon, strange disappearances occur around Mr. Mannering: first, the cat disappears and, later, his Cousin Jane. More suspiciously, the new plant’s prominent buds seem to grow in size with each strange disappearance. This densely-written story is quite thought-provoking with a touch of Kafkaesque morbidity to it, which makes it surprisingly psychological. Collier definitely took the story of the murderous orchid to a new level of disbelief and complexity.
