Recall when I found a story by the wrong Bandyopadhyay (Sharadindu and not Bibutibhushan). It was in a collection of translated
Golden Age mystery short stories called "Foreign Bodies", edited by Martin Edwards, and it contained a reasonable number of Sherlock Holmes pastiches, some of which i thought were very good. If it's in your library (it was in mine), you cuold try reading some of these stories.
