‘Well, you guessed right. What then?’

‘You might reconnoitre the ground to-morrow—the exits, there are sure to be some towards waste land or market gardens.’

‘Jolly!’ said Trevor. ‘I’ll make up as a wanderer from Suffolk, looking for a friend in the slums; semi-bargee kind of costume.’

‘That would do,’ said Merton. ‘But you had better go in the early morning.’

‘A nuisance. Why?’

‘Because, later, you will have to get a gang of fellows to be about the house the day after, when I pay my visit.’

‘Fellows of our own sort, or the police?’

‘Neither. I thought of fellows of our own sort. They would talk and guess.’

‘Better get some of Ned Mahony’s gang?’ asked Trevor.

Mr. Mahony was an ex-pugilist, and a distinguished instructor in the art of self-defence. He also was captain of a gang of ‘chuckers out.’
