Book Review ##murder

A woman is killed in an accident. A scientist is murdered in broad daylight. Yet no murderer was seen. One by one, a team of scientists on the verge of an important discovery die under mysterious circumstances. Superintendent Vijay is an ace detective who has solved many cases in the past.

When a young woman is found lifeless in a pool of her own blood, everyone is convinced that it is her college sweetheart who murdered her. Is there a connection between a missing blue envelope, a misplaced sweater and stray footprints in a room?
