Join me as I jump on a bike and hit Madrid´s streets to discover some curious secrets of the Spanish capital. I sign-up to Madrid´s Bici Madrid public cycle scheme and brave the traffic to check out some fascinating locations which hide some surprising stories. I puzzle at the Masonic symbolism on the Ministry of Agriculture building next to Atocha Station, visit the scene of the audacious assassination of Spanish prime minister Admiral Luis Carrero - whose car was catapulted over a five-floor apartment, visit Madrid´s oldest sports venue, a hidden pelota court on a leafy city street and catch a fish on Malasaña´s fishy street.
