Dick bestowed upon me one of the most superlatively cunning winks that humanity could create.

“I’ve an idea,” he curtly answered.

“Well, what is its nature?”

“Look here, McGovan, you’re a detective, and pretty fly, but you don’t come it over me so easy,” he retorted sharply, but without any anger. “I’ll swop secrets with you, there!

I made no conditions, but allowed Dick to settle his own terms. Before I gave him Mr Bannister’s name and address, I insisted on being told what hold Peter had on that gentleman, when Dick readily answered—
