The Cunning Saboteur has an unflappable air, which he certainly needs as he manages our finances. But there's a lot going on beneath the surface. He's a very crafty pool player but, like all good players, manages to look like a lucky amateur. He also dabbles in the dark pools of cryptocurrency, which really is a game for lucky amateurs. His one secret weakness, which he will only confess in interviews, is a love for Excel spreadsheets. For David, a spreadsheet is a murder mystery, a maze of clues and omissions that has to be unravelled. (We hope that someone from Excel is reading this so they know that, after all this time, they actually have a fan.) Welcome David, a man of many surprises. We can't wait to discover more.
