Greg gazed at her in silent sympathy.
The hands came down; the soft face hardened. "No time for mourning now. Since I couldn't save him, I mean to avenge him!"
"If I could tell you how sorry I am!" murmured Greg.
"Don't sympathize with me," she said quickly. "It brings the tears back. I must be hard. Help me to be hard."
"I am at your service in all ways," he said simply.
"You see what happened now?" she said.
"I am beginning to."
"I don't know yet how they killed him, but it's clear enough how they disposed of the body. That man learned in some way that it was in your cab. That is why he hired you to take him across the river. The other two men were on board the ferry too. But I paid no attention to them because I was watching him, the man in your cab. When you and he left the cab I followed you up forward. Then the other two went to the cab, of course; searched the body, and then cast it over the rail. You see now why he made you drive on last."
"Of course!"
"Planned with devilish cleverness!" she cried. "That is like him! Why weren't my eyes opened to his true character earlier! But I'll make him pay! If the body is missing, will it be possible to bring the crime home to the murderer?"
