This was no easy task. Only two men could have revealed the place. They were Flash Donegan and Dip Riker. Others, who might have told, were no longer in New York.
There were good reasons why The Shadow did not care to question either Donegan or Riker; but now, since the conversation that Burbank had overheard, it was important that The Shadow should know at once.
Burbank continued his patient waiting. He knew the situation thoroughly.
The Shadow, in his search for Donegan’s underlings, had not yet achieved his objective. Perhaps he might be in the vicinity; but he was not actually there.
Marty Jennings and Lance Bolero were in waiting for whoever might come their way. Harry Vincent was en route. A phone call to Flash Donegan would report the capture of The Shadow’s agent.
Time went by. A light glowed on the plug box beside Burbank. Instantly the man became active. Flash Donegan was receiving a call!
Burbank dialed The Shadow’s number. The response was immediate. Burbank spoke a word of explanation.
Quickly, he inserted plugs. The Shadow, on the outside, was cut in on Donegan’s wire. Burbank was adjusting a double-head phone. Through one ear, he could hear Flash Donegan’s conversation. Through the other, he could listen to The Shadow.
“That you, Marty?” said Donegan’s voice.
“Right, Flash,” came the gruff reply.
