Only one man could have placed that package there. The Shadow!
Now, Cardona realized that the man of the dark had secretly entered this room. The Shadow had placed the box beneath the sleeping detective's pillow.
To make sure that Cardona would discover it, he had taken the detective's notes from the coat pocket, and had put them with the package!
Pulling away the stems of the violets, Cardona found the object that he sought. A small flat metal disk, like the one that had brought him on his errand to Philadelphia. Like the first, this coinlike bit of metal bore a message:
Death
Through
Window
"Death through window!"
The thought took Cardona back to the scene at the Hotel Dalban, in New York. Could that be the death to which The Shadow had referred? It was the only death that interested the detective. Cardona recalled the windows of the seance room in the Dalban. Closed shutters, locked on the inside. The hotel men had said that they were always shut and locked, except when the room was being aired. Why had The Shadow sent this message to Philadelphia? A few days ago, in New York, it would have been of value. There was nothing in last night's seance — and Cardona was examining his notes carefully— that could have given a clue to the mode of entrance used by the killer in New York. Angrily, Cardona threw the violets in the wastebasket.
He saw it now! The Shadow was tricking him! He had been brought here on a futile chase, so he would be absent from New York. Perhaps some undiscovered evidence remained in that room at the Dalban. If so, it would be removed by now.
