Tulkinghorn has been alerted by an anonymous source to the uncanny likeness that SJ Berwin financial services partner David Calligan bears to Ally McBeal star John Cage. Like Calligan, Cage - aka 'the biscuit' - is a lawyer. But after that the similarities end, as Cage is a litigator while Calligan is a financial services expert. However, Calligan does act for a number of US companies, so are they, in fact, one and the same? Tulkinghorn needs one final piece of evidence: does Calligan have any frogs as mates, pick his nose or use a remote control toilet flusher? If anyone knows, please get in touch.
