Trust to my discretion . '' After some further conversation , I arranged with Antonio that he was to try and effect the escape of Uncle Richard , and , if possible , that of Dr Cazalla . The following night he was to be on guard inside the prison , and he would then have the keys in his possession . The most likely time was about ten o'clock ; and I arranged to be in the neighbourhood to assist , if necessary , in the escape of my friend . Mr Laffan approved of the plan , but thought that it would be imprudent for him and me to be seen again near the prison , although we might afterwards join the fugitives . I proposed , therefore , having horses in readiness , and making our way down to Honda , whence we might embark on the river Magdalena ; and the current being rapid , we should not occupy more than five days , and might at Carthagena get on board the first vessel about to sail . If we could once reach any of the British West India Islands , we should be safe .
