‘The man’s real name is Daniel Pearse.’
Debritto said, ‘The machine agrees, or at least that it’s a truthful guess. On what basis do you make that guess?’
Sweat trickled down Dredneau’s neck. ‘I broke a code, an extremely difficult code. From radio transmissions. It took me almost eight months. Cryptography is a useful talent for a detective. I pay listeners all over the world to monitor coded radio transmissions. Most of the codes are trifles, unraveled at a glance. This one was provocative – what’s called a shift-cipher. I had to amass a huge sample before I could establish any sort of frequency count, much less discern the operative principles; with that, the code sets followed.’
‘You’re doing well. My compliments on your work, one professional to another. So, what are these code sets?’
‘Partial panagrams – a complete set is in my valise in the bedroom.’
‘
‘I don’t know. It’s a guess. Based on style and odd textual references. It’s a group of alchemists or magicians, I think.’
‘A secret society?’
‘Perhaps.’
‘No national, racial, political affiliations?’
‘Maybe anarchists.’
‘There have always been rumors about such a group.’
‘If the code’s difficulty is any indication, they’re very careful.’
‘We’ll see. Now Daniel Pearse – why is his name a guess?’
‘Because early transmissions referred to “Danny Boy” and then changed to “Kharome.” Playing around one night, I reversed “Kharome” – still in code sets – and came up with DPearse. Logically, given the earlier Danny Boy reference, the D was likely for Daniel. I ran Daniel Pearse and Isaiah Kharome through my information network, which stretches from Interpol to the local PD – and
‘Tell me about this Daniel Pearse.’
‘His dossier is in my valise with the code sets and frequency charts. What little there is is rather provocative. When he was fourteen, his mother, Annalee Pearse, was killed and Daniel was severely injured planting a bomb. He was suddenly represented by expensive lawyers and placed under the guardianship of questionable relations. From there––’
‘Stop!’ Debritto said. ‘I hope you’re right about this, sir. I get to clean up a mess. I killed his mother.’
Dredneau said nervously, ‘My reports say a faulty bomb. Check them, please.’
Debritto ignored him. ‘It was a rush job. I wasn’t supposed to kill her; just stop her. Foil it. Those fools don’t want to punish. I mean, they didn’t even want the police to know. They didn’t say
‘Sure,’ Dredneau said wearily. ‘CIA. Did Keyes set me up or does it go higher?’
‘Please, Mr Dredneau. I don’t take orders from
‘I don’t know.’
‘Do you know anywhere he might be headed, any sense of a plan?’
‘No.’
‘Do you know where the diamond is?’
‘No.’
‘Your truths are boring me, sir. Surely if you had code access as the theft was being set up, you must at least have some idea of how he accomplished it.’
‘Some. They further disguise the code with their own idiom, but from what I gathered he was supposed to use a new nerve gas on the guards, blow the vault, and be picked up by helicopter flying under the radar. Those are the only elements of the plan – other than dates and names – I’m sure of.’
‘But he didn’t use the gas or explosive, right? So how did he do it?’
‘I don’t know.’
‘But you knew it was going to happen. My, my, Mr Dredneau, you might have warned us. But it’s much more fun to waltz in and grab some glory with stunning deductions – and no doubt grab a little money, too, while you’re at it.’
Dredneau said nothing.
Debritto smiled. ‘It makes you uncomfortable to realize how much alike we are. You want the ten million just like me. Otherwise, you would have given the CIA his real name, rather than Kharome, which he’s probably changed
