Incorrupt bodies of saints, gold ingots, a stolen head, Jewish refugees hiding in basement of a tea shop, a utopian city that was actually built, a disastrous explosion in the Metro that killed hundreds, a little-known animal cemetery, hawks nesting on skycrapers and a resucitated Christ are only a few of the "hidden" facets of the city to which the authors of the second part of "Hidden Madrid" will introudce the reader.
