‘As far as we know at present, nothing is.’
‘Then, do you think something may have been stolen?’

‘Then, you think that the man who strangled your father was also a common thief?’
‘I cannot say he was, and I cannot say he wasn’t. We have the broad fact before us that my father was murdered. It is for you to try and find out why he was murdered.’
‘I understand, Mr. Donald, that your father kept a box of private papers in his office.’
