'I well remember the unfortunate affair.'

'During my investigations I discovered that the Mercers were financed by a bank. A very wealthy and powerful bank. Valint and Balk.'

Glokta watched carefully for a reaction, but Marovia's eyes did not so much as flicker. 'I am aware of the existence of such an institution.'

'I suspected that they were implicated in the Mercers' crimes. Magister Kault told me as much before his unfortunate demise. But his Eminence did not wish me to investigate further. Too many complications at a complicated time.' Glokta's left eye twitched and he felt it beginning to run. 'My apologies,' he muttered as he wiped it with a finger. 'Shortly afterwards I was dispatched to Dagoska, to take charge of the defence of the city.'

'Your particular diligence in that matter was a source of some discomfort to me.' Marovia worked his mouth sourly. 'My congratulations. You did an extraordinary job.'

'I cannot entirely take the credit. The task the Arch Lector had given me was impossible. Dagoska was riddled with treason and surrounded by the Gurkish.'

Marovia snorted. 'One sympathises.'

'If only anyone had sympathised then, but they were busy here, trying to get the better of each other, as they always are. Dagoska's defences were in a state entirely inadequate for the task. I could not strengthen them without money—'

'His Eminence was not forthcoming.'

'His Eminence would not part with a single mark. But an unlikely benefactor stepped forward in my time of need.'

'A rich uncle? What a happy chance.'

'Not entirely.' Glokta licked at the salty space where his front teeth had once been. And the secrets begin to spill like turds from a draining latrine-pit. 'My rich uncle was none other than the banking house of Valint and Balk.'

Marovia frowned. 'They advanced you money?'

'It was thanks to their generosity that I was able to keep the Gurkish out as long as I did.'

'Bearing in mind that powerful people have no friends, what did Valint and Balk get in return?'

'In essence?' Glokta gave the High Justice an even stare. 'Whatever they wanted. Shortly after returning from Dagoska I was investigating the death of Crown Prince Raynault.'

'A terrible crime.'

'Of which the Gurkish ambassador who hung for it was innocent.'

Marovia registered the tiniest hint of surprise. 'You say so?'

'Undoubtedly. But the death of the heir to the throne created other problems, problems relating to votes in the Open Council, and his Eminence was happy with the easy answer. I tried to pursue the matter, but was prevented. By Valint and Balk.'

'You suspect that these bankers were involved in the death of the Crown Prince, then?'

'I suspect them of all manner of things, but proof is in short supply.' Always too many suspicions, and not enough proof.

'Banks,' grunted Marovia. 'They are made of air. They spin money out of guesses, and lies, and promises. Secrets are their currency, even more than gold.'

'So I have discovered. But men lost in the desert—'
