“Double Z,” thought Joe Cardona. He muttered the name as he sat by his desk. “Double Z! Will he bob up again?”
The telephone rang. Cardona answered it. He heard a strange, anxious voice at the other end asking for him.
“This is Cardona,” said Joe. “Who’s calling?”
“Matthew Wade,” came the reply.
The detective jumped at the name. Matthew Wade! One of the biggest multimillionaires in the East! A man of great influence, and tremendous holdings which he had inherited and had afterward increased.
What could Matthew Wade want?
“What can I do for you?” asked Cardona.
“Come up to see me,” replied Wade. “At my home on Fifth Avenue.”
Cardona knew the place. The man of wealth still lived in a costly mansion that had belonged to his family.
The detective wasted no time in further parley. He heard Wade’s final instructions — to make the visit confidentially. That was enough. Joe Cardona was on his way.
