But I have great hopes - in fact, the betting is exactly two to one - that if you will come with us to-night I shall be able to help you to lay him by the heels.'

'No, I fancy Chiswick is an address which is more likely to find him. If you will come with me to Chiswick to-night, Lestrade, I'll promise to go to the Italian Quarter with you to-morrow, and no harm will be done by the delay. And now I think that a few hours' sleep would do us all good, for I do not propose to leave before eleven o'clock, and it is unlikely that we shall be back before morning. You'll dine with us, Lestrade, and then you are welcome to the sofa until it is time for us to start. In the meantime, Watson, I should be glad if you would ring for an express messenger, for I have a letter to send and it is important that it should go at once.'
