‘Well deserved, I am confident,’ said Logan; ‘and now you are sure that you know exactly what you have to do, as I have explained?’

‘Yes, I am to be walking through Albany Grove at a quarter to four on Friday.’

‘Be punctual.’

‘You may rely on me,’ said Miss Frere.

Logan next day went to Trevor’s rooms in the Albany; he was the capitalist who had insisted on helping to finance the Disentanglers. To Trevor he explained the situation, unfolded his plan, and asked leave to borrow his private hansom.

‘Delighted,’ said Trevor. ‘I’ll put on an old suit of tweeds, and a seedy bowler, and drive you myself. It will be fun. Or should we take my motor car?’

‘No, it attracts too much attention.’

‘Suppose we put a number on my cab, and paint the wheels yellow, like pirates, you know, when they are disguising a captured ship. It won’t do to look like a private cab.’

‘These strike me as judicious precautions, Trevor, and worthy of your genius. That is, if we are not caught.’

‘Oh, we won’t be caught,’ said Trevor. ‘But, in the meantime, let us find that place you mean to go to on a map of London, and I’ll drive you there now in a dog-cart. It is better to know the lie of the land.’
