Ellery met “the Spaniard” in accordance with his appointment in Trafalgar Square that evening. As he approached, he saw the old man pacing up and down the pavement in front of the National Gallery, walking slowly with a dignity and grace worthy of some grandee of the olden times. He was curiously like the Lavery portrait of Cunninghame Graham. “The Spaniard” made Ellery a low bow, accompanied by a sweeping gesture with his broad-brimmed hat; and Ellery, doing his best to live up to the occasion, returned the salutation with a very inferior grace. “You have news for me?” he asked. “If you will do me the honour of accompanying me in my promenade, I think I may be able to impart certain facts of interest to your fair lady.” “The Spaniard,” as Ellery told Joan afterwards, took the devil of a time to come down to brass tacks. But what he had to tell was quite conclusive. He had found, and could produce, conclusive evidence that Walter Brooklyn had been in Trafalgar Square at the time he had stated. He had discovered two men who had seen him leaning over the parapet opposite the National Gallery, and one of them had definitely noticed the time by the clock of St. Martin’s Church. This had been at 11.40. Moreover, the second man, perhaps, “the Spaniard” hinted—oh, so delicately that his way of saying it seemed to make petty larceny a fine art—in the hope of picking a few trifles out of Mr. Brooklyn’s pockets, had actually followed him round the Square, and seen him take out his watch and look at the time. He had shadowed Brooklyn up Cockspur Street and the Haymarket, actually as far as the corner of Jermyn Street, where some object of greater immediate interest had served to distract him from the chase. Moreover, in return for suitable rewards, both these men were prepared to give evidence. “The Spaniard” had arranged for them both to meet Ellery, if he so desired, and, in a few minutes’ time, they would be in the bar of the little public-house in which Ellery had originally met with “the Spaniard” himself. This was more than satisfactory, and Ellery at once went to meet the two men and hear their stories. They fully bore out what “the Spaniard” had said, and Ellery took their names and addresses, and then arranged to see them again on the following morning at the same place, and to take them, with the other witnesses he and Joan had collected, to Thomas’s office, where they would be able to consider the steps that had best be taken towards securing Walter Brooklyn’s absolution. He could get hold of the remaining witnesses later in the evening; but first he had to thank “the Spaniard” and to settle with him for what he had done.
