But now, the fact that he had not called on the lawyers had put a different complexion on the affair. Also his statement concerning the money left to him was proved--by the evidence of the solicitors who paid the annuity--to be a lie. Robin therefore had not been so deeply plunged in grief as he appeared to be, when he could call a few days after his mother's death to see if he was to inherit the money. Herrick considered that probably when alone in the flat he had found some paper stating that the five hundred a year terminated at his mother's death, and had gone to Frith and Frith in order to ascertain if this were true. Besides his mother might have told him this on her deathbed. But what else had she told him? Colonel Carr was not the man to pay out money for nothing. Mrs. Joyce must have had some hold over him. However the main point, and that which vexed Dr. Jim most, was the fact that Robin had not called on the solicitors, as he said he had done. At Southberry he had received a letter calling him up to town. Jim had not read the letter, but since Robin had told him the contents he never doubted that it was from the firm of Frith. If he had not called on them, why was the letter sent, and where was he during the two days he was in Town? Herrick reckoned back the dates. It was Thursday the twenty-sixth of July when they arrived at Saxham. Robin had gone to Town on the twenty-fourth, and on that same night Colonel Carr (according to the medical evidence) had been shot. "Good Heavens!" said Jim when this came into his mind, "can it be possible that Joyce killed the man? There is no reason why he should. I am a suspicious fool. He was in London even though he did not call on the solicitors. There is no proof that he was at Saxham. He said himself when he went through the Pine wood that he did not know the country." Then Jim recollected that it was Robin who had selected the route for the walking tour. Could it be possible that he knew of the existence of the House in the Pine Wood, and had designedly led Herrick that way in order that the murder should be discovered, and suspicion averted from himself? "No! No!" Cried Jim tossing and turning, "he could not have contrived so damnable a scheme. Besides he slept at the Hull Hotel." In this way he kept arguing out the situation, but by the morning he had come to no conclusion. The evidence against Robin was not strong enough. But while shaving Dr. Jim made up his mind to call on Frith and Frith, and also to look in at the Hull Hotel. Nevertheless whatever he found, he resolved to hold his tongue so far as Robin was concerned. Joyce was far too intimate with Don Manuel to please Herrick. And Don Manuel, as the doctor remembered professed a hatred of Carr. He also might have something to do with the matter. "Stephen" said Herrick at breakfast, "I want you to look after yourself again to-day. I have business to do."
