"Look hard, then. For I want to get Mac cleared as soon as it can be brought about."
"We'll hope to do that. I'm going over to the Studios now, and I've a notion I'll discover something."

"His cough syrup hasn't been touched lately. The dried up stickiness of the cork shows that. And one or two other bottles are in the same condition. But in the waste basket in his bedroom I found this."
She held up an empty bottle that was labeled soda mints.
"There's a new full bottle in the medicine chest," she went on, "and as this was in the basket, mayn't it be that he took the last ones, and——"
"And they were poisoned!"
