Query: The k-in-a-path problem for claw-free graphs   Testing whether there is an induced path in a graph spanning k given vertices
is already NP-complete in general graphs when k=3. We show how to solve this
problem in polynomial time on claw-free graphs, when k is not part of the input
but an arbitrarily fixed integer.
