"Cahill are used to going on extremely dangerous missions, but sometimes they need a little extra help. That's why Sinead Starling created this robot spider. It can be used as a scout for agents who need to know what's around the next corner-you never know where a Vesper could be lurking. This tool is extremely expensive, but that didn't stop Dan from using the spider for less official purposes...like sending it to find Amy's diary."
