"Thank you. I appreciate warnings. So I'll say Hewitt hereafter. The time came when Harry Gould's suspicions regarding the card became more definite. Again I don't know why, but my surmise is that he learned about the loss of the most valuable plantation of broad-leaved evergreens in the country-the rhodalea plantation of the Updegraff Nurseries of Erie, Pennsylvania-by an attack of the Kurume yellows. He knew that Hewitt was inordinately proud of his own broad-leaved evergreens, and that he was capable of abnormal extremes in horticultural pride and jealousy. He also, being a gardener, knew how easy it would be, with a bag or two of contaminated peat mulch, to infect another plantation if you had access to it. At any rate, his suspicion became definite enough to cause him to go to Salamanca, which is in the western part of New York near the Pennsylvania border, not far from Erie, and see the proprietor of the Nelson Garage. That was in December. He learned that when Hewitt had gone there with his car months before, damaged in an accident, he had been accompanied not by a woman, but by a man of a certain description, with a cast in his eye. He went to Erie and found the man among the employees of the Updegraff Nurseries. His name was Pete Arango."
Fred Updegraff started up with an ejaculation.
Wolfe showed him a palm. "Please, Mr. Updegraff, don't prolong this." He turned. "And Mr. Hewitt, I'm being fair. I'm not trying to stampede you. I admit that much of this detail is surmise, but the main fact will soon be established beyond question. I sent a man to Salamanca last night, partly to learn why Harry Gould had so carefully preserved an old garage job-card, and partly because he had written on the back of it that name Pete Arango, and I knew that Pete Arango was in the employ of the Updegraff Nurseries. My man phoned me this morning to say that he will be back here at one o'clock, and the proprietor of the Nelson Garage will be with him. He'll tell us whether you were there with Pete Arango. Do you suppose you'll remember him?"
"I'll-" Hewitt swallowed. "Go ahead."
