The boy who remembered a golden fortress
In 'Sonar Kella', young Mukul Dhar of Calcutta draws a golden fortress and speaks of hidden jewels he claims to remember from a past life, and word of this reaches the newspapers. Two crooks hear about the treasure, get rid of the real parapsychologist escorting Mukul to Rajasthan, and one of them takes his place. Feluda follows them across the desert to Jaisalmer's sandstone fort, the 'golden fortress', and exposes the impostor before Mukul can lead the crooks to anything.
