Irrespective of his success or failure, however, if Grantley had in any manner influenced Baldwin to take this step, he had acted in a way that no reputable surgeon would have dreamed of doing.

On the other hand, it was quite possible, of course, that Baldwin had acted purely on his own initiative, in order to show, by his prompt payment, the gratitude he felt for his returning sight.

It was another delicate and trying situation.

In the end, Nick advised the secretary to make out the check and send it as requested. There were no obstacles in the way of this, for the millionaire, who had the utmost confidence in his secretary, had signed several checks in blank before entering the private hospital.

Nick reasoned, that, if all was straight, the secretary might get into serious trouble with his dictatorial employer if he failed to carry out the latter’s instructions to the letter. Besides, a quarter of a million was only a drop in the bucket compared with the immense bulk of Baldwin’s fortune. If the millionaire had come to any harm, the money loss would quickly pale into insignificance.

Lastly, the giving of a check and the payment of it are two very different things. Payment of it could be stopped, if necessary; or, on the other hand, the rapidity with which Grantley might try to realize on it, or the use to which he might put it, could be turned to advantage as an indication of the game being played.

It went against the grain, but the check was made out and sent without further delay.

That was on a Friday.

Nick at once set a watch over both Grantley’s bank and Baldwin’s, but they closed on Saturday, without any attempt having been made to catch or deposit the big check.

The delay gave the detective a more favorable impression than anything else had done, for it seemed to show that Grantley was in no hurry to take advantage of the payment, and that implied that the surgeon had no intention of trying to disappear.
