When he reached the end of High Street, he was jerked out of his reverie by something that sprung up before him to demand his attention. Cardiff Castle was a daunting structure. Beginning as a Roman fortress, it had been rebuilt by the Normans then extended and embroidered by successive owners. Some of its interior had fallen into disrepair but its high walls and massive gatehouse remained. For hundreds of years, it had dominated the town completely. Cardiff was now slowly fighting back, surrounding it with houses, encroaching on its margins, laying siege architecturally. A castle with a town had become a town with a castle. Colbeck took a few minutes to appraise it and to speculate on how much misery its dungeons must have known in the time when they were the home of any local malefactors.

Turning right and with the castle on his left, Colbeck strode in the direction of the Theatre Royal. Stockdale had told him that it was situated in Crockerton but that turned out to be his pronunciation of Crockherbtown. It was only a short walk from the castle. What had once been a leafy suburb of Cardiff was now an integral part, linked to the centre by a series of houses, shops, inns, chapels and other buildings. Colbeck had not gone very far beyond the castle when he was accosted by a young woman whose bonnet framed a face of exceptional loveliness.

'May I give you one of these, sir?' she said, sweetly, offering him a playbill. 'Buckmaster's Players are performing here this week.'

'I know,' he said, taking the handbill and glancing at it. 'As it happens, I'm on my way to the theatre right now to speak to Mr Buckmaster.'
