Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos.

A sinister case of deadly poisoned chocolates from Sodbury Cross's high street shop haunts the group of friends and relatives assembled at Bellegarde, among the orchards of 'peach-fancier' Marcus Chesney. To prove a point about how the sweets could have been poisoned under the nose of the shopkeeper, Chesney stages an elaborate memory game to test whether any of his guests can see beyond their 'black spectacles'; that is, to see the truth without assumptions as witnesses. During the test - which is also being filmed - Chesney is murdered by his accomplice, dressed head to toe in an 'invisible man' disguise. The keen wits of Dr Gideon Fell are called for to crack this brazen and bizarre murder committed in full view of an audience. Also known by its US title The Problem of the Green Capsule, this classic novel is widely regarded as one of John Dickson Carr's masterpieces and remains among the greatest impossible crime mysteries of all time.

The Hispanic rite, a medieval non-Roman Western liturgy, was practiced across the Iberian Peninsula for over half a millennium and functioned as the most distinct marker of Christian identity in this region. As Christians typically began every liturgical day throughout the year by singing a vespertinus, this chant genre in particular provides a unique window into the cultural and religious life of medieval Iberia. The Hispanic rite has the largest corpus of extant manuscripts of all non-Roman liturgies in the West, which testifies to the importance placed on their transmission through political and cultural upheavals. Its chants, however, use a notational system that lacks clear specification of pitch and has kept them barred from in-depth study. Text, Liturgy and Music in the Hispanic Rite is the first detailed analysis of the interactions between textual, liturgical, and musical variables across the entire extant repertoire of a chant genre central to the Hispanic rite, the vespertinus. By approaching the vespertini through a holistic methodology that integrates liturgy, melody, and text, author Raquel Rojo Carrillo identifies the genre's norms and traces the different shapes it adopts across the liturgical year and on different occasions. In this way, the book offers an unprecedented insight into the liturgical edifice of the Hispanic rite and the daily experience of Christians in medieval Iberia.
